Learning orfogrammy "alternating vowels in the root of the word"

In Russian there orthograms "alternating vowels."Word, obeying this rule writing can not be verified by matching single-root words, as in the case unaccented the root word.Their writing is sometimes dependent on the consonant that follows orthograms from the word or suffix used.Often such words cause trouble at school, so the teacher should be given more time learning the rules.

roots where there are alternating vowels, it is desirable to learn by heart and be able to distinguish them from other morpheme, similar in sound or spelling.

Choice spellings depends on several factors.In zor-, zar unstressed (eg Dawn) is fundamentally on the letter indicated by the letter A, and in the opposite case (for example Dawns) - O. The exception in this case is the word zoryanka indicating the name of the bird.

alternating vowels in the roots of mountain, harmonic, klan-, klon-, creative, tvar-: A written under the stress (tan, bow, creature), and in the unstressed position O (tan, lean,do).Exceptions are the

words of utensils, slag, metal penetration.You also need to pay attention to the roots and smooth plov-.In the words of them written In the case of unstressed (float fin and so on. D.).The exceptions are nouns swimmer and swimmer.It's worth noting that the word "Quicksand" is written at the root of "Y" sound respectively.

widespread cases when alternating unstressed vowel consonant depend on ending morpheme.These are the words with roots lag, false, rast, growth, cascade, kosn-.For example, suppose - suppose to grow - grow and others. There is a word-exceptions that must be memorized.For example, growth, sprout, curtains and so on. D.

Some words alternating vowels are chosen depending on the value of the root.So, for example, is determined by writing the words to the IOC, the maxi-.If the parts of speech used in the sense of "getting wet, to leak," the IOC is used (to get wet in the rain to soak the laundry).When the root means "to immerse in something" is used maxi- (to dip into the water).

This rule applies to him, which include such parts as rovn- and ravn-."O" is written in an unstressed position, if meant to "smooth, smooth."Root ravn- use when we mean "the same, equal."For example: to compare the expression level road.

students to consolidated orthograms "alternating vowels in the root", exercises should be selected so that they included words with different cases of writing.It is important for children to repeat periodically exceptions.They are not so much for this orfogrammy, simply remember why.And the periodic fixing material for the students should be working to determine exactly what the letter should be in the word.

should be mentioned that some roots (Berman, Burma, der, dir- etc.) Are written according to the suffix, which is after him.In this case, if there -a-, then inserted the letter and otherwise - E. For example, the gain - takes will tear - tears and so on. D.
