Tasks for these spellings are present in the Unified State Examination.
Immutable prefixes
They are always written the same way.
You need to know them by sight:
in-, in-, inzo-, you-, do-, for-, iso-, on-, over-, necessary-, not-, under-, o-, about-, about-, over-, over- , sub-, sub-, pra-, pre-, pro-, dis-, s-, co-
in/climbed, in/went, climbed/went, you/climbed, up/drove, for/laugh, out/tear, to/left, over/build, must/tear, not/true, under/write, o/ task, about/rub, about/angry, from/cut, from/tear, over/jump, over/jump, under/underground, call/call, great/grandson, pre/election, about/read, make/anger, with/to do, with/to call.
(N10) Vowels and consonants in prefixes (except for prefixes with z(s))
- Unstressed vowel in prefixes
(except for pre-/pre-) in an unstressed position the vowel that is heard in the same prefix under stress is written. To check, you need to choose another word with this prefix, where it is stressed:
from/grow — From/shine, on/tear - on/away
- On consoles rose-/grown-
— times-/ras
- written under stress O, and without accent A:
R A list - p ABOUT write off,
R A call - r ABOUT call me,
R A pour - r ABOUT rash.
But, wanted (from the wanted list). - Consonant in prefixes
, except for prefixes ending in z-/s-, the one that is heard in the same prefix before a vowel or before is written v, r, l, m, n
.
To check, you need to choose another word with this prefix, where comes before a vowel or v, r, l, m, n (in this position the dubious consonant is heard clearly):about/rub - about/grow, about/search; under/drag - under/chapter, under/search.
Prefixes for Z-/N-
without-/without-, with-/with-(sun-/sun-), from-/is-, bottom-/nis-, times-/ras, rose-/ros-, through/through (through/through).
-
Spelling roots with I - Y after consoles
- If the prefix ends in a consonant, then AND the root changes to Y
:
And gra-roses s grysh, And famous - without s famous, And history - prev s story.
- But, after the consoles inter-, over-
and foreign language prefixes dez-, counter-, post-, sub-, super-, trans-, pan
— AND
does not change:
above And refined, between And institute, dis And infection, counter And gra, post And impressionism, trance And Indian, pan And Islamism
Excl.: charge.
Double consonants at the junction of roots and prefixes
- at the junction of the prefix and the root of a word, double consonants are formed if the prefix ends with a consonant and the root begins with the same letter:
be salary abotny, without/star, demon/mortal, be s/s glorious, call, rise, ra s/s vet, by d/d keep d/d believe, be salary busy, be s/s sticky, once/call, angry/angry.
- calculation, calculating, calculate - console dis- added to the root - even (deduction, odd, subtract), except countless ;
- calculate, calculated - console dis- added to base -counts, which already has a prefix With- (v/s/chit/a(t), count, count out).
- Quarrel - two letters s, not three (to quarrel), because In Russian, three identical consonants in a row are not written.
- In words to tear apart, to tear apart, to ruin and there are no prefixes derived from them - one letter h.
- (No. 6) The dividing b is written only after consonant prefixes before the letters e, e, yu, i, denoting two sounds (the sound [th’] appears):
entrance, exit, announcement; take away, flaw, embrace, immense, embrace (historically the root -i-).
Pre-/Pri- prefixes
- The prefixes PRE- and PRI- in the unstressed position are pronounced the same, but differ in meaning and spelling.
(No. 29) If the prefix denotes accession, approach, proximity or incomplete action, then the letter i- is written in it (prefix prefix-). And if the prefix is close in meaning to the word very or to the prefix pere-, then the letter e is written in it (prefix pre-).
Console The value that determines the choice of prefix Examples AT- approximation at/to go, at/tide, at/swim accession to/to sculpt, to/to sew, to/glue addition when/build, when/draw being near (near something) at/road, at/city, at/school incompleteness of action when/sit down, when/open, when/slow down, when/decorate bringing an action to its logical conclusion at/talk, at/cook, at/think, at/beat performing an action in someone's interests with/hide, with/own, with/keep PRE- meaning close to the meaning of the words very, extremely pre/unpleasant, pre/pretty, pre/kind close to the meaning of the prefix PERE- interrupt (interrupt), block (block) - Remember

§38. In accordance with the general rule (see §33), the writing of letters in place of unstressed vowels in prefixes (except for the prefix raz-/roz-, see §40) is established by checking words and forms with the same prefix, in which the vowel being tested is under accent, for example:
weak-willed, talentless, careless, stupid (cf. be?zdar, stupid);
freeze, bring?, lock, record (cf. locked, record);
transfer, distort, transfer, shift, rewrite (rewrite, transferred, distorted);
take away, unlock, tear off, set aside (o?took, o?tper);
put, sign, cut, approach (by? signature, by? approach);
run, miss, miss, break through, rub (miss, miss, break through); great-grandmother (great-grandfather).
Note1. Words with the foreign-language prefix peri- should be distinguished from words with the prefix peri-, for example: perige?y, perice?ntr (astronomy terms), pericard?t, periton?t (medical terms), perisco?p, peripete?ya, periphrase or periphrase (a philological term; hence the verb to paraphrase, but cf. paraphrase 'to say, to state differently').
Note2. At the end of foreign language (Latin) prefixes ultra- and extra- an unverifiable letter a is written, for example. ultra-revolutionary, extraordinary, extrovert. However, in words with the Latin prefix intra- (intro-) the spellings with the letters a and o differ: cf., for example, intrazonal, intramolecular and introjection, introscopy, introvert.

Unstressed vowels in prefixes
In this lesson we will learn how to write words with unstressed vowels in prefixes without errors.
When a vowel sound is stressed, it is in a strong position, that is, it is clearly heard. In an unstressed position, the vowel sound is pronounced indistinctly - this is its weak position. Let's remember what the rule for checking unstressed vowels sounds like:
The accent, like a magic wand, dispels the vowels and makes them clear and clear:
This is how we act when we check unstressed vowels at the root. Maybe this rule will help us in the case of unstressed vowels in prefixes?
Let's take a word with an unstressed vowel sound in the prefix and try to find words of the same root for it in which this unstressed sound becomes stressed.
For these words, we were able to select cognate words with an accented prefix. But there are very few such words in our speech.
Z_run - z_run, z_run, z_run. D_became - d_became, d_rate. Standing - standing, standing. We see that the vowel in the prefix was unstressed and remains so. This means that the verification method that we used when working with the root does not suit us. Consider the following words:
In the words of the first column there are prefixes with unstressed vowels, in the words of the second column there are prefixes with stress. What the words have in common is that the vowels in stressed and unstressed prefixes are written the same way. This means that the prefixes just need to be remembered.
There are several words with the prefix great-: great-grandmother, great-grandfather, great-grandson, great-granddaughter and with the prefix pa-: flood, stepson, stepdaughter. In these cases, the emphasis falls on the prefix, and you will not be mistaken in writing it.
Russian language lesson in 3rd grade on the topic
“UNStressed VOWELS IN PRESETS.”
Subject: Spelling letters of unstressed vowelsin consoles.
Target:
– development of skills to observe the spelling of vowel lettersin prefixes, distinguish between stressed and unstressed vowels in prefixes, establish patterns of their spelling;
– developing the ability to write letters of unstressed vowels in prefixes.
Organizing time

Are you ready to start the lesson?
Is everything in place, is everything okay?
A book, pen and notebook?
Checked, sit down!
– Open your notebook.
– What should you write down? (Date.)
Commented number entry.
– What entry should be made next?
– Write the words “Cool Job.”
Self-determination for educational activities.
(Motivating students for learning activities through analysis of the lesson motto)
“Always learn, know everything! The more you learn, the stronger you will become." (M. Gorky)
Why do we have such a motto today?
Can they be attributed to you?(Yes, the more we learn, the stronger we will become in our knowledge...)
How are these words related to our lesson? (We will learn something new and become stronger in our knowledge.)
Do you want to become stronger?(Yes )
Then give a smile and wish each other good luck!(clap each other's hands)
You guessed it, today we have a lesson in discovering new knowledge, which means you and I will be engaged in educational activities.
While in the learning activity, we will complete two steps of the learning activity(Step 1 – I don’t know; Step 2 – I’ll find a way myself)
A minute of penmanship.
Guys, we have serious work ahead of us in class today, so let’s set ourselves up positively for the lesson and prepare our hands for writing. Open the notebook and place it correctly on the table. Let's write down the number, class. slave. Where do we start our Russian language lesson? (A moment of penmanship.)
Pay attention to the screen. Look carefully at the syllable field and find the letter combination that appears in every line of this field?
(on the)
Write down the combinationon on the next line in your notebook.(pay attention to the connection of letters) . Using a simple pencil, highlight the best combination in your opinion.

Updating knowledge and recording difficulties in individual activities.
First, we must repeat what we already know.
- Are we going to repeat everything?
- No, only what we need.
Let's remember which part of the word we started learning in the previous Russian lesson?(Console ).
- Which part of the word do the letter combinations in your notebook remind you of?(prefix )
Let's work in pairs.
Each of you has a table on your desk. Fill in the first column in the table. Write everything you already know about the console (time 1 minute)
The prefix is part of ………….
The console costs.....
The attachment is used for……..

examination
What skills did we develop?
– How to detect a prefix in a word?
– Give examples of words with prefixesBy- Andunder - .( showing cards with prefixes By- Andunder )
– What word with a prefixunder- from test task No. 2, topic 4
in the workbook you chose? (Snowdrop .)
– Prove that this word has a prefix.
Formulating the problem, planning activities.
Write down the words. Place emphasis
Flew, ran, wrote, caressed, danced
Read the words. How are these words similar?(these are verbs)
Copy the words, insert the missing letters, and put an emphasis on each word.
Underline the vowel letters in unstressed syllables.
In what part of the word is it located?Label these parts of the word.
Which spellings can you explain and which cannot?
We need to solve this problem in class today.
– Formulate the topic of the lesson. (Letters of unstressed vowels in prefixes.)
Statement of a problematic question.
Now we will act as researchers. Let's open the textbooks and find the exercise. 147
In order for it to be completed quickly and successfully, we will complete the task in pairs.
Each row explores four words
Performed (if necessary) with the consultation of a teacher.
Each pair will draw a conclusion: where the letters of unstressed vowels can be located, what spellings can be explained.
Conclusion : unstressed vowels can be not only in the root, but also in prefixes. Basically they can be verified .
– What about unstressed vowels in prefixes?
Let's formulate the main question of the lesson (express their assumptions )
Compare your guesses with the textbook on p. 171
Let's define the goals of our lesson (attach cards to the board one by one)
1) Learn to correctly write words with an unstressed vowel in the prefix.
2) Create an algorithm for writing unstressed vowels in a prefix.
What question do we have to answer now? (How to check an unstressed vowel in a prefix)
Let's fill in the second column in our table
A prefix is part of a word
The prefix comes before the root
It is written together with words
Where do you think you can get the correct answer, how to write a word?/ In the textbook, in the dictionary, in the encyclopedia, ask the teachers, mom and dad /.
– What were we doing now? (We formulated the topic of the lesson, made a plan, planned our activities.)
7. Finding a solution.
a) Work from the textbook.
- So, basically we already know how to check an unstressed vowel, what should we do with unstressed vowels in prefixes? What do you think should be done to correctly write an unstressed vowel in a prefix?
Does anyone have any suggestions?
How can we test our assumptions?
1. Let's check your assumptions by performing exercise. 148
What do stressed and unstressed prefixes have in common? (they are identical)
What conclusion can we draw? (prefixes with and without stress are written the same way, sSo, to write the letter of an unstressed vowel in a prefix, you can select a test word with the same prefix where the vowel would be stressed.
Physical education minute.
Let's check if our assumptions are correct. Let's read the rule in the textbook on p. 123.
Why are some prefixes given in parentheses? (They are similar to the previous ones, but at the end one more vowel letter is addedO – for ease of pronunciation: updated/called, bit/teared off, ran/approached.)
Did the assumption made by your classmates about the correct spelling of unstressed vowels turn out to be correct or not? Prove your answer.
What else did you learn from the rule that we didn’t expect? (the spelling of an unstressed vowel in a prefix can be checked or remembered)
- How? (You need to choose a word so that this vowel in the prefix is stressed).
- Should the test word always have the same root? (No ).
– When are words with the same root required for verification?
(To check the spelling of letters of unstressed vowels in the root.)
- At this stage of the lesson, what goal have you achieved?
(We learned how to correctly write an unstressed vowel in a prefix).
What goal have not yet been achieved? (We haven’t compiled an algorithm for writing unstressed vowels in prefixes).
Let's try to create an algorithm for writing unstressed vowels in prefixes.
c) Drawing up an algorithm for writing unstressed vowels in prefixes.
- Where will we start working on writing an unstressed vowel in a prefix?
Emphasize
Determine in which part of the word there is a discrepancy between pronunciation and spelling.
What does it mean? (Highlight its parts in the word).
If the unstressed vowel is in a prefix, then choose a test word with the same prefix so that the vowel is stressed.
If a test word cannot be found, then you need to remember this word, consult a dictionary, use a template word, or look it up on the Internet
Write down the word.
Emphasize the unstressed vowel in the prefix.
Who can tell him the whole algorithm for writing an unstressed vowel in a prefix?
What goal have you achieved at this stage?
Let's write the keywords in column 3 of our table
A prefix is part of a word
The prefix comes before the root
Serves to form new words
It is written together with words
How to check an unstressed vowel in a prefix?
Choose a word with the same prefix under stress
Remember
Consult the dictionary
Use a template word
Internet
Let's get back to the exercise. Make up a sentence using any word from this exercise.
Write down the sentence yourself.
Take the pieces of paper lying on your desks. Who guessed what needed to be done?
A
O
Name the prefixes in which the vowel O is written? vowel A? Well done!
Why are there empty arrows? (Not all consoles were recorded)
Do you think we have learned everything about spelling prefixes today? Why do you think so?
And again there are empty arrows? Why? There are a lot of consoles; in one lesson we will not be able to get acquainted with all the consoles. We will continue to get to know each other and fill out our cards in the next lessons.
FISMUTKA:
Game "Yes, no"
Clap and sit down once,
If the word has a preposition.
And they heard the prefix.
They named her well.
Let's go, to school, cross, through the gate, run, draw, on the grass, about a cat, throw it away, add some, outside the window.
8 . Primary consolidation
Now we have gained new knowledge.
a) Game “Clap-top”.
- Let's play with you a little. I read statements. If you agree with them, clap, if you don’t agree, stomp.
The root is the main part of speech
The root is the main part of the word
The prefix is always written together with the word
The prefix can be written either together with the word or separately
The prefix can come after the root
The prefix always comes before the root
Unstressed vowels occur only in the root. (top).
The spelling of unstressed vowels in prefixes needs to be memorized or checked by choosing a test word with a stressed prefix. (clap).
Test words must necessarily have the same root. (top).
In a wordlock there is a prefix-behind
In a worda note there is a prefix -behind
b) Selective recording of words with the studied spelling .
– Write down the words with the spelling “Letter of an unstressed vowel in a prefix”, label it.(words on slide)
The bird's trill rang,
The carousel spun.
One two three four five,
The bunny went out for a walk.

) is established by checking words and forms with the same prefix, in which the vowel being tested is under stress, for example:
weak-willed, mediocre, careless, stupid(cf. mediocrity, stupidity);
freeze, enter, lock, record(cf. locked, recording);
transfer, distort, transfer, shift, rewrite (census, transferred, distorted);
take away, unlock, tear off, set aside (took away, unlocked);
put, sign, trim, approach (signature, approach);
run, miss, miss, break through, rub (miss, miss, broken through); great-grandmother (great-grandfather).
Note 1. From words with a prefix re- words with a foreign prefix should be distinguished peri-, eg: perigee, pericenter(terms of astronomy), pericarditis, peritonitis(medical terms), periscope, peripeteia, periphrase or paraphrase(philological term; hence the verb paraphrase but cf. paraphrase"to say, to put it differently").
Note 2. At the end of foreign language (Latin) prefixes ultra- And extra- an uncheckable letter is written A, eg ultra-revolutionary, extraordinary, extrovert. However, in words with the Latin prefix intra- (intro-) spellings differ with letters A And O: Wed, e.g. intrazonal, intramolecular And introjection, introscopy, introvert.
§. Pre- and pre- prefixes. The writing of these prefixes follows a general rule; both prefixes occur under stress: cf. tether, attack, sound, whistle, arrived, dowry, summoned And interrupted, betrayed. The application of a general rule requires taking into account the different meanings of these prefixes.
The prefix has the following basic meanings:
proximity, direct adjacency to something, for example: Primorye, Baltic States, coastal, roadside, border, Ural, Volga;
approximations, additions, eg: run, move, attach, attach, attribute, buy;
incompleteness of action, for example: open, lift, sit down, cheer up, extinguish;
bringing an action to a certain result, for example: prepare, accustom, caress, shame, reconcile, try on;
in verbs with the suffixes -yva- (-iva-), -va- the meaning of the accompanying action, for example: to say, to dance, to sing.
The prefix pre- in combination with adjectives and adverbs denotes a high degree of quality, for example: kind, very nice, most unpleasant, disgusting, very calm, enough. In verbs, the prefix pre- denotes an action that manifests itself to a high degree ( to be filled, to exalt, to prosper), or has meanings close to the meanings of the prefix re-( interrupt, refract, block, endure). In words like exceed, satiate, overabundance, the prefix denotes excessiveness, going beyond the limits of something.
In some words, the meaning of the prefixes pre- and prine is not entirely clear or their identification is questionable, for example: p observe, teach, pursue, present, convey, elderly, free, fit, handsome, fancy, order, hello. The spelling of such words is determined in dictionary order.
Note 1. Prefixes in verbs differ exaggerate, increase and in paired verbs that are close in meaning downplay And downplay. Verbs exaggerate And downplay with attachment pre- have the meaning of “to imagine something in larger (smaller) sizes than it actually is.” Verb increase means “to multiply, increase even more”, and downplay -"reduce somewhat."
Note 2. The spelling of other similar or similar-sounding words with prefixes also differs pre- And at-, eg: abide(Where) - arrive(Where), betray(someone or something) - give(to whom; to what), limit - chapel, successor - receiver, receiver; bow down (knees, head) And bow down - bow down) “bending (bending over), bringing closer, leaning against something.”; transgress(What) - start(for what), implement(what) - pretend(what) and pretend; transitory - coming, endure - endure, indispensable - inapplicable, repose - attach, immutable - attach.
§. Console times- (ras-) / rose- (ros-). Contrary to the general rule, in this prefix the letter a is written in place of the unstressed vowel, and under the stress - o, for example: distribute (cf. distributed, distributed), schedule, receipt (painting), scatter, scatter, loose (scatter), spill, pour (bottling), search, search (search), kindle (kindle), dissolve (dissolve), play (draw) ).
§. At the end of prefixes and prepositions ending in a consonant or consisting of only one consonant, in some cases an unstressed vowel appears before combinations of consonants, represented in writing by the letter o, for example: bend (cf. bend), enter, enter, entered (enter), tear off (tear off, tear off), send (send), break off (break off, break), disassemble (disassemble, disassemble, parse), accelerate (accelerate, accelerate), similarity (knock out ), develop (develop), erase (erase), die off (die); without everything (cf. without money), in everything (in the new), in me (in us), with our own (with us), in front of me, above me (in front of you, above you), to everyone (to you). Such an unstressed vowel prefix is checked in the stressed position in the forms of passive participles past. vr. some verbs ( bent, sent, torn, disassembled), as well as in some adverbs, for example: on time, I'll go blind.
