Russian word formation: one root, many words

Russian words are built like Lego from four kinds of part: a prefix at the front, a root carrying the core meaning, one or more suffixes, and a grammatical ending. Learn the parts and a single root opens up a dozen words.

Read the parts in order and the meaning assembles itself, just as English “under-write”.
The short answer

Find the root first: it carries the meaning. Prefixes add direction or completion, mostly to verbs. Suffixes change the word’s class: a verb becomes a person (-тель), an idea (-ние) or an adjective (-ный). Diminutive suffixes make things small or dear. The ending only shows grammar: case, gender, person.

1 · Roots

Word families: pick a root and see what grows from it

A root is the core of a word that its relatives share. Its vowel or final consonant can shift slightly (пис / пиш, ход / хож), but you will still recognise it. Each word below is split into its parts.

2 · Prefixes

Fourteen prefixes and what they add

Prefixes mostly attach to verbs. They do two jobs at once: they add a meaning (in, out, across, finished), and they usually make the verb perfective, the “completed result” form. Many have a matching preposition: в (into) and в-, из (out of) and вы-.

PrefixAdds the idea ofWith писа́ть, to write (or нести́, to carry)With ходи́ть, to go on foot
в- (во-) in, into
вы- out, out of
при- arrival, attaching
у- away, removal
пере- across; again; over
до- as far as, to the end
за- start; behind; a brief stop
от- (ото-) away from; off
под- (подо-) under; approaching
про- through; past; a while
раз- / рас- apart, in all directions
с- (со-) down; together
об- (обо-) around
на- onto; enough; completion

Before some consonants a prefix gains a vowel: в → во (войти́), с → со (сойти́), под → подо (подошёл). Prefixes ending in з change to с before a voiceless consonant: рас-сказа́ть, but раз-говор.

3 · Noun suffixes

From verbs and adjectives to nouns

A suffix after the root turns one kind of word into another. Each suffix also fixes the noun’s gender, so learning the suffix tells you how the noun will behave.

People
Actions and ideas
Places and things
4 · Adjective suffixes

Turning a noun into an adjective

English often puts one noun in front of another: “winter coat”, “city centre”. Russian usually turns the first noun into an adjective instead. Four suffixes do most of the work; a consonant at the end of the root may change before them (рука́ → ручно́й).

NOUN+ SUFFIX + ENDING = ADJECTIVEIN A PHRASE зима́зимнийзи́мнее пальто́ zi-MAZEEM-niyZEEM-ni-ye pal’-TOwinterwinter (adjective)winter coat
пальто́ is neuter, so the adjective takes the neuter ending -ее.
-н-the most common: “of, relating to”
-ск-places, nations, people
-ов- / -ев-materials, plants, things
-лив- / -ив-a tendency, a trait
5 · Diminutives

Small and dear: -ик, -очка, -енька

A diminutive suffix makes a word mean “small”, and very often “dear” or “cosy” as well. Russians use them constantly, with food, children, animals and in polite requests: Мину́точку! (Just a moment!). The gender stays the same as the original noun.

SuffixGenderPlain wordDiminutiveFeel
-ик masculine домhouse a little, cosy house
-чик masculine стака́нglass a small glass
-ок masculine сырcheese a cheese snack
-ка feminine рука́hand a little hand; also: pen, handle
-очка / -ечка feminine мину́таminute just a moment (polite)
-ушка feminine ба́баold woman grandmother (now its own word)
-ко neuter молоко́milk a little milk (to a child)
-енький adjective ма́лыйsmall small, little (the everyday word)
Names: from formal to tender

Every Russian first name has a short everyday form and several affectionate ones. The full name is for documents and strangers; the short form for friends; the affectionate forms for family and children.

Full · formalShort · friendsAffectionateVery tender
6 · Compounds and abbreviations

Two roots joined with о or е

A compound joins two roots into one word, linked by -о- (after a hard consonant) or -е- (after a soft one). The second part usually decides the meaning, as in English “steam-boat”. Russian also forms words from the first letters or syllables of long names.
