Rules governing the spelling of the roots, in the course of the Russian language is not so much.Unstressed vowels in the root morpheme in some cases, the emphasis is checked, in others - such verification is not possible, and remember the spelling of a word by heart.
to words that contain alternating vowels in the root, do not get to use any of the algorithms of action.
appearance of words with alternating (both vowels and consonants) scientists explain a number of changes that occurred in the ancient Slavic language long before the advent of writing.
orfogrammy complexity of this is that, in addition to storing a long list of conditions and the roots themselves public elections, we must be able to distinguish words with alternation in the root of the words, they are similar.To avoid errors in the application of a set of rules on alternating vowels in the root of the word, is to learn the roots of the job their semantics (ie, value).The roots of alternating -dimensional and -mir- matter "immobility" and the homonymous "beginning" in the word "peace", "tolerate" and "fitting" checked accent.
As the job usually "alternating vowels in the root" is included in the final attestation work on the Russian language, the topic worth investigating.At a minimum, in order to successfully pass this examination.
Thus, the roots of alternating can be divided into four groups.In each of these selection conditions vowel are different.
In the first group selection depends on the last letter:
- -raST (W) / growth (vegetation, nurtured, growing);
- -skaK / skoCh- (jump, jump);
- -laG / false (excl .: canopy).
second group should pay attention to the stress.
In unstressed position, select About in the following roots:
- -gar / mountainous (excl .: Prigara, slag);
- -klan / klon-;
- -tvar / creative (excl .: utensils).
Conversely, without the stress we choose And the roots:
- -zar - / - zor- (excl .: zorevat and zoryanka);
- -plav - / - plov- (excl .: quicksand, swimmer and swimmer).
alternating vowels in the root of the third group are dependent on the lexical value:
- -mak - / - IOC
root -mak- contained in the words of the value of immersion in the liquid, and the root with O - "wet".
example: dip the bread in the milk, wet boots.
- -ravn - / - rovn- (excl .: Plain, the same age level)
-ravn- have root word meaning "same" or "equal" and -rovn- - "smooth" or "flat".
example: insoluble equation, flat trajectory.
In the fourth, the very roots of volume group to which the rule "alternating vowels in the root of the word", spelling depending on the subsequent suffix -A-.If the word we see this suffix, then write in the root and:
- -ber / Burma (you take, climbing);
- Perot / PIR (unlocked, unlocked);
- -der / dir- (tears up, lifts);
- ter / tir- (it is rubbing, rubbing).
Examples: He chose a long time, lock the door at night or not locked.
Fearing that he vyderut tooth, Bob was running away from doctors.
wipe off the dust in the room or wipe?
- -zheg / zhig- (ignite, incitement);
- -stel / stil- (spreads, spread out);
- -chet / chit- (deduction, subtract);
- -kos / cascade (touches, touches).
example: I expected that barely touches the flame from the lighter paper spread out, the fire flares up again.
- -dimensional - / - peaceful;
- -blest - / - blist-.
froze with admiration, we looked at the brilliant game actors .
As we can see, usually, "alternating vowels in the root" is not very complicated.After learning the roots of the group and the selection criteria of vowels in them, each graduate will improve your chances to pass the final exam on the Russian language for a high score.
