This is the highest-leverage page in the word-formation section, because Ukrainian noun suffixes do two jobs at once: each one tells you what kind of noun you're looking at (a person who does X? an abstract quality? the action itself?) and it tells you the gender, which controls every ending the noun will ever take. Learn that -ник makes a male agent and is masculine, that -ість makes an abstract quality and is always feminine, and that -ення makes an action/result and is neuter — and you can read a word you've never met, guess its meaning, and decline it correctly, all from the last three or four letters. That is an enormous shortcut, and it is the organising idea of this page.
Agent suffixes: the person who does X (masculine)
The "doer" suffixes turn a verb or a noun into the person who performs it. They are all masculine by default, and they are the most generative group in the language.
-ник is the workhorse, attaching to verbs and nouns alike: робо́та → робітни́к "worker," пожежа → пожежник "firefighter," худо́жник "artist," праці́вник "employee," бо́рг → боржни́к "debtor." Note the frequent consonant softening at the seam.
Кожен робітни́к на цьому заво́ді прохо́дить тижне́вий ку́рс безпе́ки.
Every worker at this plant goes through a week-long safety course. — робо́та → робітни́к 'worker.'
-ач / -яч typically builds an agent (or sometimes an instrument) from a verb: чита́ти → чита́ч "reader," виклада́ти → виклада́ч "lecturer," гляді́ти/дивитися → гляда́ч "viewer / spectator," слу́хати → слуха́ч "listener."
Кожен гляда́ч у за́лі затаї́в по́дих пе́ред фіна́льною сце́ною.
Every viewer in the hall held their breath before the final scene. — диви́тися/гляді́ти → гляда́ч 'viewer.'
-ар / -яр marks occupations, often manual or craft ones: бджола́ → бджоля́р "beekeeper," шко́ла → школя́р "pupil," бібліоте́ка → бібліоте́кар "librarian," and the irregular-looking but everyday лі́кар "doctor." (лі́кар is stressed on the first syllable, unlike most -ар words.)
Наш сільський лі́кар знає кожного пацієнта на ім’я́.
Our village doctor knows every patient by name. — the agent noun лі́кар 'doctor.'
-ець (with stem form -ц- when it inflects) builds members of nations, groups, and again agents: Украї́на → украї́нець "a Ukrainian (man)," продава́ти → продаве́ць "salesman / seller," боре́ць "fighter," співе́ць "singer (poetic)." The е of -ець is a "fleeting vowel": it disappears in the oblique cases — украї́нець, but украї́нця, украї́нцеві.
Цей продаве́ць пора́див мені́ деше́вший, але кра́щий телефо́н.
This salesman recommended me a cheaper but better phone. — продава́ти → продаве́ць, the е dropping in продавця́.
A smaller agent suffix, -тель, is more bookish: учи́ти → учи́тель "teacher," писа́ти → письме́нник (here actually -ник), дослі́джувати → дослі́дник. The classic -тель word is учи́тель.
Female counterparts: -ка and -иця (feminine)
For most agent nouns Ukrainian forms an explicit feminine with -к(а) or -иц(я), and these are feminine nouns. This is fully productive and increasingly preferred for women in any profession.
| Masculine (agent) | Feminine | Meaning |
|---|---|---|
| учи́тель | учи́телька | teacher |
| робітни́к | робітни́ця | (female) worker |
| украї́нець | украї́нка | Ukrainian (woman) |
| співа́к | співа́чка | singer |
| львів’я́нин | львів’я́нка | person from Lviv |
Моя́ сестра́ — учи́телька матема́тики, а її́ подру́га — лі́карка.
My sister is a maths teacher, and her friend is a doctor. — учи́тель → учи́телька, лі́кар → лі́карка.
Ця робітни́ця пропрацюва́ла на фа́бриці три́дцять ро́ків.
This (female) worker has worked at the factory for thirty years. — робітни́к → робітни́ця, with к → ц.
Abstract-quality suffixes: -ість, -ство, -ота (feminine / neuter)
To name a quality or state — the abstract "-ness / -ity" of an adjective — Ukrainian reaches above all for -ість, attached to an adjective stem. The single most important fact about it: every -ість noun is feminine, and they all decline alike (third declension, soft). From any adjective you can build one: шви́дкий → шви́дкість "speed," незале́жний → незале́жність "independence," можли́вий → можли́вість "possibility," відповіда́льний → відповіда́льність "responsibility," ра́дий → ра́дість "joy."
Мене́ найбі́льше врази́ла його́ відповіда́льність і спо́кій.
What struck me most was his sense of responsibility and his calm. — відповіда́льний → відповіда́льність, abstract quality, feminine.
У ме́не є мо́жливість прийти́ за́втра, якщо тре́ба.
I have the possibility / chance to come tomorrow, if needed. — можли́вий → можли́вість, feminine.
-ство / -цтво builds abstract or collective nouns and is neuter: брат → бра́тство "brotherhood," ми́тець → мисте́цтво "art," бага́тий → бага́тство "wealth / riches," студе́нт → студе́нтство "the student body." Note that -ство after a т/ц/ч stem assimilates to -цтво (мисте́цтво, коза́цтво).
Украї́нське мисте́цтво ба́рокко лиши́ло по собі́ дивови́жні собо́ри.
Ukrainian Baroque art left behind astonishing cathedrals. — ми́тець → мисте́цтво, neuter abstract noun.
A smaller, less productive quality suffix is -ота (feminine): добро́ → добро́та "kindness," те́плий → теплота́ "warmth," краси́вий → (relatedly) красота́ / краса́. Treat -ота as a closed list you recognise rather than one you freely build.
Action and result suffixes: -ння / -ення / -ання (neuter, doubled)
To turn a verb into the noun of its action or result — the equivalent of English "-ing / -tion" — Ukrainian uses -ння, in the shapes -ання (from -ати verbs) and -ення (from -ити/-іти verbs). Two facts make this group instantly recognisable: every such noun is neuter (ending in -я), and the н is doubled — written нн — which on the doubled-consonants page you learn to pronounce as a genuinely long [n]. These are the verbal nouns (also called gerunds).
| Verb | Verbal noun | Meaning |
|---|---|---|
| чита́ти | чита́ння | reading |
| бажа́ти | бажа́ння | wish, desire |
| пита́ти | пита́ння | question |
| завда́ти / - | завда́ння | task, assignment |
| навча́ти(ся) | навча́ння | study, learning |
| зна́чити | зна́чення | meaning |
| рішати/вирішувати | рі́шення | decision |
Чита́ння перед сном — найкра́ща звичка, яку я набу́в цього ро́ку.
Reading before bed is the best habit I picked up this year. — чита́ти → чита́ння, neuter, doubled нн.
Учи́телька дала́ нам скла́дне завда́ння на вихідні́.
The teacher gave us a hard assignment for the weekend. — завда́ння 'task,' neuter verbal noun.
Яке́ зна́чення цього сло́ва в цьому ре́ченні?
What's the meaning of this word in this sentence? — зна́чити → зна́чення 'meaning.'
Watch the doubling: it is wrong to write чита́ня with a single н. The long нн is the orthographic signature of this whole class (and it survives in pronunciation — say it long).
A few more useful types
Diminutive suffixes (covered fully on the diminutives page) shrink and soften: -ок / -ик / -к(а) / -очок — ліс → лісо́к, стіл → сто́лик, кни́га → кни́жка, син → сино́чок. The diminutive keeps the gender of its base.
Place suffixes name where an activity happens, mainly -ня / -арня: ї́сти → їда́льня "dining hall / canteen," пекти́ → пека́рня "bakery," ліка́рня "hospital," перука́рня "hairdresser's." These are feminine.
Сту́денти обі́дають у їда́льні на пе́ршому по́версі.
The students have lunch in the canteen on the ground floor. — ї́сти → їда́льня 'dining hall,' a -ня place noun.
The consonant mutations at the seam
As warned in the word-formation overview, the root's final consonant often mutates before a suffix. The three core swaps are г → ж, к → ч, х → ш (the "first palatalisation"), and before some suffixes г → з, к → ц, х → с (the "second"). They are regular, and recognising them keeps you from missing the root.
| Base | Derived | Mutation |
|---|---|---|
| друг 'friend' | дру́жба 'friendship' | г → ж |
| рука́ 'hand' | ручни́й 'manual' (adj.) | к → ч |
| ву́хо 'ear' | ву́шко 'little ear' | х → ш |
| робітни́к | робітни́ця 'female worker' | к → ц |
Між на́ми зав’яза́лася спра́вжня дру́жба ще зі шкі́льних ро́ків.
A real friendship grew up between us back in our school years. — друг → дру́жба, г → ж.
Source-language comparison
For an English speaker, the headline is that the suffix carries gender, which English nouns don't have at all. In English "reader," "speed," and "reading" are all just nouns; in Ukrainian their suffixes simultaneously sort them into masculine (чита́ч), feminine (шви́дкість), and neuter (чита́ння), and that sorting governs every adjective and verb that agrees with them. So the suffix isn't decorative — it's load-bearing grammar. The second surprise is how routinely you mark a profession's gender: where English says "she's a teacher," Ukrainian strongly prefers учи́телька, the explicitly feminine form, and using the masculine for a woman now sounds dated.
For a Russian speaker, the suffixes rhyme with Russian but diverge in detail and that is where errors leak. Ukrainian's quality suffix is -ість (not Russian -ость: незале́жність, not независимость), its verbal nouns favour -ння with the doubled н (чита́ння, not чтение), and the feminine -ка/-иця forms are more freely used. Build from the Ukrainian shapes, and respect the doubling.
Common Mistakes
❌ чита́ня.
Incorrect — the verbal noun doubles the н: чита́ння. The doubled нн is obligatory in this whole class.
✅ чита́ння.
reading — neuter verbal noun with the doubled нн.
❌ незале́жністю (treated as masculine).
Incorrect gender — every -ість noun is feminine: незале́жність declines as third-declension feminine (instr. незале́жністю is right, but it agrees as feminine).
✅ Украї́нська незале́жність.
Ukrainian independence — -ість is feminine, so the adjective is feminine українська.
❌ Вона́ вчи́тель.
Disfavoured for a woman — Ukrainian prefers the explicit feminine: вона́ вчи́телька.
✅ Вона́ вчи́телька.
She's a teacher — the feminine -ка form is the natural choice.
❌ продаве́цьа (keeping the е in the oblique case).
Incorrect — the е of -ець is fleeting and drops: продаве́ць, but продавця́ in the genitive.
✅ продаве́ць → продавця́.
seller → of the seller — the fleeting е disappears in oblique cases.
Key Takeaways
- A noun suffix encodes meaning type + gender at once — read the tail and you predict both.
- Agents (the doer, masculine): -ник (робітни́к), -ач/-яч (чита́ч), -ар/-яр (бібліоте́кар, лі́кар), -ець (украї́нець, with fleeting е).
- Female counterparts (feminine): -ка / -иця (учи́телька, робітни́ця) — now the preferred way to name a woman's profession.
- Abstract qualities: -ість is always feminine (шви́дкість, незале́жність, можли́вість); -ство/-цтво is neuter (мисте́цтво).
- Actions / results: -ння / -ення / -ання are neuter with the doubled нн (чита́ння, завда́ння, зна́чення, рі́шення).
- Expect consonant mutations at the seam (г→ж, к→ч, х→ш; к→ц): друг → дру́жба, робітни́к → робітни́ця.

- Word Formation: How Ukrainian Builds WordsB1 — Orientation to словотві́р, Ukrainian word-building — the four engines that let you decode and create vocabulary instead of memorising it one word at a time: PREFIXES (за-, пере-, не-, роз-), SUFFIXES (the productive workhorse: учи́тель, чита́ч, шви́дкість, чита́ння), COMPOUNDING with the linking vowel -о-/-е- (землеро́б, життє́пис, паропла́в), and conversion. From one root like ро́бота 'work' you get робітни́к 'worker', робо́чий 'working', заробля́ти 'to earn', переробля́ти 'to redo' — so learning the affix toolkit multiplies your vocabulary.
- Adjective and Adverb SuffixesB2 — The suffixes that turn nouns and verbs into adjectives, and adjectives into adverbs — and the insight English speakers miss: where English glues two nouns together ('school bag', 'wooden table'), Ukrainian must first turn the first noun into an adjective (шкільни́й рюкза́к, дерев’я́ний стіл). RELATIONAL: -н(ий) (лісни́й), -ов-/-ев- (бузко́вий), -ськ-/-цьк-/-зьк- (украї́нський, коза́цький, пра́зький, with consonant changes). MATERIAL: -ан-/-ян- (дерев’я́ний). QUALITY: -лив- (щасли́вий), -ист-/-аст- (барви́стий), -уват- 'somewhat' (синюва́тий). AFFECTIONATE: -еньк-/-есеньк- (гарне́нький). ADVERBS: -о/-е (га́рно, до́бре) and по-…-ому/-ськи (по-украї́нському, по-украї́нськи).
- Grammatical Gender: Masculine, Feminine, NeuterA1 — Ukrainian sorts every noun into three genders — masculine, feminine, neuter — and you can predict which about 90% of the time from the nominative singular ending; gender then drives all adjective, pronoun, and past-tense agreement, so it must be learned with each word.
- Doubled (Lengthened) ConsonantsB1 — Ukrainian writes certain long consonants as doubled letters — життя́, знання́, ні́ччю — and they are pronounced genuinely LONG. The doubling is phonemic, mandatory, and clusters predictably in the neuter -я noun class and the soft-feminine instrumental, so you can predict it rather than memorize each word.
- Diminutives and AugmentativesB1 — Ukrainian builds an enormous range of evaluative nouns by suffix — diminutives (-ок, -ик, -чик, -ка, -очка, -ечко, -ечка) that add smallness and especially warmth (ко́тик, со́нечко, хлі́бчик, до́нечка), and augmentatives/pejoratives (-ище, -исько, -юга, -яга) that add largeness or contempt (вовчи́ще, злодю́га) — and these are pragmatically expected in everyday speech, child-talk, and endearment far more than anything in English.
