Vowel alternation in the root of the word

For a start, it will be helpful for each of us to figure out what is the root of the word? A root is a morpheme - a part of a word, according to which single-root words are combined into one group.That is, if you change a word, incline it, add prefixes, suffixes, the root will not change and will have the same spelling in all the same type words. For example, the word "genus" is the whole word and is the root, and if you try to pick up the same-root words, you will get a whole group of words with the same meaning:birth, relatives, relatives, kinship, kinship, parents, relatives, nature, germ- in all words, one root - "genus". However, the roots in single-root words are not always written in the same way, in some of them you will find an alternation of consonants, for example:arm(root -hand-) and single-root word manual (root -hand-). There is also an alternation of vowels in Russian, for example, the already known berber - / - bir-. The rule of alternating vowels in these roots is quite simple, you can see this with examples.root ber bir rule

The rule of alternation in the roots -ber - / - bir-

One rule obeys 9 + 1 roots:

-ber - / - bir- -per - / - pir- -steel - / - steel
-der - / - dir

-ter - / - shooting

-check - / - chit-
- burn - / - burn -mear - / - world- - brilliant - / - shine

You can see that all these nine roots are interleaved with vowels "and" and "e", but, apart from the roots - ber - / - bir -, the rule includes another root, the tenth with alternating vowels "o" and "a" - -cos - / - cas-.

-Ber - / - bir-: rule, examples

ber ber rule ruleTo determine which letter should stand in these roots, you need to pay attention to the suffix. If after the root there is a suffix "a", then you need to write the letter "i" in the root, for the root -kos - / - kas - the letter "a", if the suffix is ​​"a" no, you need to write the letter "e" or "in the root o "(for root -kos - / - kas-). Examples:

you take - voter prop up to move - to spread
tear apart - tear apart erase - erase subtract - subtract
burn out burn out kill - die shine - shine
touch - touch

The table shows the root β-ber - / - ber. The rule that explains writing in this root and in a group of similar roots is not so difficult to learn. It is enough to remember the combination -ber - / - bir-, and the remaining roots will change according to a pattern. However, ber - / - bir - is a rule that has its exceptions. In the words "marriage", "phrase", "combination" and "couple" the letter "E" is always written. It is much easier to remember the exception to the rule, if you put a few of these words in a short story. For example: "The phrase" combination of the four "will tell you about their marriage."
