Fluent vowels in root, suffix and prefix

Let’s find out what fluent vowels are. Here are examples of words of different parts of speech with fluent vowels “o”, “e” in the root, suffix and prefix.

What are fluent vowels?

When the grammatical form changes or when new words are formed in different morphemes, some vowels or consonants can be replaced by others. This is called interleaving. Let’s take an interest in examples of alternating vowels and consonants.

Sometimes the alternation of the vowels “o” and “e” can occur with zero sound. This means that in a word or its form between the consonants, a vowel “o” or “e” may appear where it did not exist before, or, conversely, disappear. We are talking about fluent vowels, for example:

  • p about in – there is no (what?) a ditch;
  • tent – many (what?) chambers about;
  • box o k – edge (what?) box;
  • courtyard e c – steps (what?) of the palace;
  • man e k – silhouette (who?) man.

Examples of words with fluent vowels in the prefix

If the prefix ends in a consonant, and the root of a word is often a cluster of two or more consonants, then for the convenience of pronunciation, a fluent vowel “o” appears in the prefix, for example:

  • ras to spread – spread to spread;
  • to disperse to drive – once a gon;
  • Sun walk – rise;
  • to tear – to tear;
  • to drive away – to drive away;
  • from taking – from taking;
  • to drive – to drive;
  • to walk – to go;
  • in pouring – in pouring;
  • to take – to take;
  • over tear – you need to tear.

Fluent vowels at the root of the word

Fluent vowels “o”, “e” are observed in the root of nouns in the form of genitive singular and plural.


  • forehead – forehead, forehead, foreheads;
  • sleep – sleep, dreams, dreams;
  • mouth – mouth, mouths, mouths;
  • ice – ice, ice, ice;

Fluent vowels in roots and suffixes of nouns and adjectives

Unstressed fluent and connecting vowels.

The correct spelling of a letter in place of an unstressed vowel in some cases is determined by the fluency of this vowel.

A fluent vowel appears in many nouns and adjectives in one of the declension forms, between two final consonants of the stem (as part of a suffix or root).

A fluent vowel is present in those forms where there is no ending (in the forms with the so-called zero ending), namely: for nouns husband. genus II declension – in the form of them. n. units h (bag – bag, father – father); in nouns of I declension and environments, genus II declension, as well as in some nouns that have only plural forms. h., – in the form of genus. n. pl. hours (sister – sisters, intestine – intestines, ring – rings, day – days); for quality adjectives – in short singular form. h. husband. kind (strong – strong – strong, smart – smart – smart); for possessive adjectives with the suffixes -y and -achiy (-achy) – in the form of them. n. units h. husband. genus (fox – fox – fox, feline – feline – feline). In all other forms of declension of the listed groups of words, there is no fluent vowel.

A fluent vowel can also appear not in a separate form of a word, but in another related word (in all its forms), for example: needle – needle, needle; glasses – glasses; taiga – taiga; Moscow – Moscow, Moscow region; one hundred – hundredth, hundred; ship – ship, shipbuilder; war is military; benefit – useful; casting – foundry, foundry; minister – ministerial, ministry.

Fluent vowels are found in both stressed and unstressed positions. Under the stress, fluent vowels o (in the letter also transmitted by the letter ё) and e are usually common. The vowel and is rarely found (one – one, egg – eggs, number – digit). In this case, before the d (as opposed to the unstressed position, see § 64, p. 3 and p. C), the letter e is written here, in accordance with the pronunciation, for example: nightingale – nightingale, family – families, family and family, friends (plural) – friends, cell – cell and cell attendant, whose – whose, third (third) – arbitrator, draw (noun) – no man’s.
