We disassemble the subject: "Alternating vowels at the root of the word"

The rules regulating the spelling of roots, in the course of the Russian language is not so much. The vowel in the root morpheme is checked by stress in some cases, in others - such verification is impossible, and the spelling of a word is memorized by heart.

To words that contain alternating vowels in the root, none of the action algorithms can be applied.

The appearance of words with alternation (both vowels and consonant sounds) scientists explain a number of changes that occurred in the language of the ancient Slavs long before the appearance of writing.

The complexity of this orthogram is that, in addition to memorizing a long list of roots themselves and the conditions for choosing a vowel, one must be able to distinguish words with alternation at the root of words similar to them. In order to avoid mistakes in the application of the code of rules to alternating vowels in the root of a word, one should learn the roots without detaching them from their semantics (that is, meaning). The roots with alternation -mer- and -mir- have the meaning of "immobility", and the homonymous "beginnings" in the words "world", "reconcile" and "fitting room" are checked by accentuation.

Since the task for the rule "alternating vowels at the root" is included in the final attestation work on the Russian language, the topic should be understood. At least in order to successfully pass this exam.

So, the roots with alternation can be divided into four groups. In each of them the conditions for choosing a vowel differ.

In the first group, the choice depends on the last letter:

• -past (N) / roC- (vegetation, nurtured, growing);
• -skAK / SCOCH (jumps, jump up);
• -lA / LOZ- (excl.: Canopy).

The second group should pay attention to stress.

In an unstressed position, choose O in the following roots:

• -gar / mountains- (excl .: pickle, cinders);
• -clan / clone;
• -tware / creative- (excl. Utensils).

And, conversely, without stress, we choose A in the roots:

• -p - / - zor- (exc: zorevat and zoryanka);
• -float - / - pilaf- (excl.: Quicksand, swimmer and swimmer).

Alternating vowels in the root of the third group are depending on the lexical meaning:

• -mac - / - mok-

The root-mak- is contained in words with the meaning of immersion in a liquid, and the root with 0 is "wet".

For example: dunk bread in milk, wet boots.

• -equal - / - level (excl: plain, coeval, level)

Root-Equal-have words with the meaning "equal" or "equal", and -run- - "smooth" or "even".

For example: an insoluble equation, an even trajectory.

In the fourth, the most voluminous group of roots, to which the rule "alternating vowels in the root of the word" applies , the spelling depends on the subsequent suffix -A-. If in the word we see this suffix, then we write in the root AND:

• -ber / bir- (take, climb);
• -per / pir-(unlock, unlock);
• -der / dir- (it is tearing, tugging);
• -ter / tir- (rub, rub).

Examples: He chose for a long time, to lock the door for the night or not to lock.

Afraid that he would lose a tooth, Vasya ran away from the doctors.

Wipe the dust in the room or wipe it?

• -zheg / zhig- (light, ignition);
• -style / stil- (spreads, spreads);
• -cost / chet- (deduction, subtract);
• -cos / cassette (touches, touches).

For example: I expected that hardly the flame from the cigarette lighter would touch the spread newspaper, the fire would again flare up.

• -mer - / - world-;
• -blast - / - blist.

Fading with admiration, we looked at the brilliant play of actors .

As we see, the rule "alternating vowels in the root" is not very complicated. After learning the root groups and the conditions for choosing the vowels in them, each graduate will increase their chances to pass the final exam in Russian to a high score.
