The Ukrainian apostrophe ’ is part of the spelling of a word, exactly like a letter — leaving it out is a spelling mistake, not a stylistic shortcut. The conceptual why (it marks a hard consonant plus a /j/ glide, the mirror image of the soft sign) is covered on the apostrophe page; this page is the practical decision procedure: given a word, do you write ’ or not? There is one test, three places where the answer is "yes," and a short list of traps where the answer is "no." Get this page automatic and you will spell м’я́со, п’ять, об’є́кт and з’ї́сти correctly every time — and stop adding stray apostrophes to бюро́ and бу́ря, where they do not belong.
The one test, then the three "yes" places
The apostrophe is only ever written before an iotated vowel — я, ю, є, ї — and only when the consonant in front of it stays hard and a /j/ is heard. That happens in exactly three situations.
1. After the labials б, п, в, м, ф
The labials cannot be palatalized before a following iotated vowel in native Ukrainian words, so the glide has to be spelled out with an apostrophe:
м’я́со
meat — hard м + /j/ + /a/.
п’ять
five — hard п + /j/ + /a/.
в’юн
loach (a fish); also a wriggly, restless person — hard в + /j/ + /u/.
здоро́в’я
health — hard в + /j/ + /a/.
ім’я́
(first) name — hard м + /j/ + /a/.
верф’ю́
(with a) shipyard — instrumental of верф, hard ф + /j/ + /u/.
Бері́ть бі́льше о́вочів — це ва́жливо для здоро́в’я.
Eat more vegetables — it's important for your health.
Як тебе́ зва́ти? Яке́ в те́бе ім’я́?
What should I call you? What's your name?
2. After hard р
After р, the apostrophe marks the difference between a hard р + glide (apostrophe) and a soft р (no apostrophe). This is the famous minimal contrast:
бур’я́н
weed — hard р + /j/ + /a/.
пі́р’я
feathers, plumage — hard р + /j/ + /a/.
ма́тір’ю
(with a) mother — instrumental of ма́ти, hard р + /j/ + /u/.
Весь горо́д заро́с бур’яно́м, тре́ба полоти́.
The whole garden's overgrown with weeds, we need to do some weeding.
Contrast this with a genuinely soft р, which takes no apostrophe — see the trap section below (бу́ря, ряд, Рябко́).
3. After a prefix ending in a consonant
When a prefix like з-, об-, від-, під-, роз-, без- meets a root that starts with an iotated vowel, the morpheme boundary is marked with an apostrophe so the vowel keeps its full /j/:
з’ї́зд
congress, convention — prefix з- + ї.
об’є́м
volume (capacity) — prefix об- + є.
об’є́кт
object — prefix об- + є.
від’ї́хати
to drive off, depart — prefix від- + ї.
під’ї́зд
entrance, stairwell of an apartment block — prefix під- + ї.
роз’ясни́ти
to clarify, explain — prefix роз- + я.
без’я́дерний
nuclear-free (e.g. a nuclear-free zone) — prefix без- + я.
За́втра ми з’ї́мо торт, а сього́дні тре́ба попрацюва́ти.
Tomorrow we'll eat the cake, but today we have to get some work done.
The prefix case ties directly into the з-/с- prefix spelling: the prefix keeps its consonant, and the apostrophe sits at the seam between prefix and root.
Where you must NOT write the apostrophe
This is the half learners skip, and it is exactly where the grading is strict. If the consonant is genuinely soft, there is no /j/, and there is no apostrophe — the softness is shown by the iotated vowel itself.
After a soft consonant, the iotated vowel just softens it (no glide, no apostrophe):
бу́ря
storm — soft р + /a/, NO glide, NO apostrophe (contrast бур’я́н, hard р).
ряд
a row, a series — soft р + /a/, no apostrophe.
ря́ска
duckweed — soft р + /a/, no apostrophe.
свя́то
holiday, celebration — soft в + /a/, no apostrophe (the labial is soft here).
цвях
a nail — soft в, no apostrophe.
морква́
carrot — soft в, no apostrophe.
In many borrowings the consonant softens before ю/я, so again no apostrophe is written:
бюро́
bureau, office — soft б + /u/, no apostrophe.
пюре́
purée, mash — soft п, no apostrophe.
кюве́т
roadside ditch — soft к (before ю), no apostrophe.
гра́вюра
engraving — soft в, no apostrophe.
After a soft р inside a name or word there is no apostrophe either:
Рябко́
Ryabko (a common dog's name) — soft р, no apostrophe.
So the pivot is the same in every case: бу́ря (soft р, no apostrophe) vs бур’я́н (hard р, apostrophe); свя́то (soft в) vs здоро́в’я (hard в). Same letters, opposite behaviour — and only your ear (or memory) for hard-vs-soft tells them apart.
The summary table
| Situation | Apostrophe? | Examples |
|---|---|---|
| After labials б п в м ф (hard) + я ю є ї | yes | м’я́со, п’ять, в’юн, здоро́в’я, ім’я́, верф’ю́ |
| After hard р + я ю є ї | yes | бур’я́н, пі́р’я, ма́тір’ю |
| After a consonant-final prefix + я ю є ї | yes | з’ї́зд, об’є́м, від’ї́хати, під’ї́зд, роз’ясни́ти, без’я́дерний |
| After a genuinely soft consonant | no | бу́ря, ряд, свя́то, цвях, морква́ |
| After a soft labial in a borrowing | no | бюро́, пюре́, кюве́т, гра́вюра |
Source-language comparison
English speakers carry over two unhelpful instincts. First, the English apostrophe is droppable punctuation (you can text "dont" and still be understood); the Ukrainian apostrophe is load-bearing spelling, on the same footing as a letter — omitting it is an error every reader notices. Second, English has no hard/soft consonant contrast at all, so the very thing the apostrophe encodes (this consonant stays hard, a /j/ follows) has no English analogue — you cannot "hear your way" to it from English habits and must learn the labials-plus-hard-р test deliberately.
For Russian speakers the separating job is familiar, but the sign is different: Russian uses the hard sign ъ at prefix boundaries (объект, съесть) and writes labial + glide differently. Ukrainian has no ъ whatsoever and does all of this work with the apostrophe — so Russian объе́кт is Ukrainian об’є́кт, and Russian съесть is Ukrainian з’ї́сти. Never reach for ъ.
Common Mistakes
❌ мясо, пять, имя
Incorrect — labials before я take the apostrophe: м’я́со, п’ять, ім’я́.
✅ м’я́со, п’ять, ім’я́
meat, five, name.
❌ бюр’о, пюр’е, комп’ютер→ but бюро has none
Incorrect for бюро́/пюре́ — these soft-labial borrowings take NO apostrophe: бюро́, пюре́ (комп’ю́тер DOES, because its п is hard).
✅ бюро́, пюре́, комп’ю́тер
bureau, purée, computer — first two no apostrophe, third with one.
❌ св’ято, бур’я (adding ’ to soft consonants)
Incorrect — свя́то has a soft в and бу́ря a soft р, so NO apostrophe; the apostrophe marks hard consonants only.
✅ свя́то, бу́ря
holiday, storm — soft consonants, no apostrophe.
❌ объєкт, зьїсти (using the Russian ъ or ь at a prefix seam)
Incorrect — Ukrainian has no ъ and does not use ь here; the prefix boundary takes the apostrophe: об’є́кт, з’ї́сти.
✅ об’є́кт, з’ї́сти
object, to eat up.
❌ Typing a straight quote: м'ясо, з'їзд
Incorrect in careful writing — use the typographic apostrophe ’ (U+2019), not the straight ASCII quote: м’я́со, з’ї́зд.
✅ м’я́со, з’ї́зд
meat, congress — curly typographic apostrophe.
Key Takeaways
- The apostrophe is spelling, not punctuation — omitting it is a graded error.
- Write ’ before я ю є ї when the consonant is hard with a /j/ glide: after labials б п в м ф (м’я́со, п’ять, здоро́в’я), after hard р (бур’я́н, пі́р’я), and after consonant-final prefixes (з’ї́зд, об’є́м, від’ї́хати, без’я́дерний).
- Write nothing when the consonant is soft: бу́ря, ряд, свя́то, морква́, and the soft-labial borrowings бюро́, пюре́, кюве́т.
- The pivot pairs to memorise: бу́ря / бур’я́н, свя́то / здоро́в’я — same letters, opposite hardness.
- Ukrainian has no ъ; use the apostrophe at prefix seams (об’є́кт, not объект). Use the typographic ’ (U+2019).

- The Apostrophe (Апостроф)A1 — The Ukrainian apostrophe ’ is a full orthographic sign, not punctuation: it marks that a hard consonant is followed by an iotated vowel (я ю є ї) pronounced with a clear /j/ glide — blocking the softening that would otherwise happen. It is written after the labials б п в м ф and after р, and after consonant-final prefixes.
- The Soft Sign ЬA1 — The soft sign ь (м’який знак) spells no sound of its own — it marks that the preceding consonant is soft (palatalized). It appears word-finally and before consonants, only after д т з с ц л н дз, never after a vowel or at the start of a word, and it is the exact opposite of the apostrophe.
- Soft Sign Spelling RulesB1 — The spelling-side rules for ь: write it after soft д т з с ц л н дз word-finally and before a hard consonant, in the -ський/-цький/-зький suffix, in -еньк-/-оньк- diminutives, in the verb ending -ться, and before о — but NOT after ж ч ш щ, NOT after labials or р at word end, and NOT after a vowel. The Russian instinct to soften final hushers and labials produces the most common wrong soft signs.
- Spelling the Prefixes З-/С- and DoublingB2 — Two spelling systems. The prefix is spelled с- before the voiceless к п т ф х (сказа́ти, спита́ти, схова́ти — mnemonic «кафе Птах»), and з- everywhere else (зроби́ти, зекономити), with зі- before clusters (зібра́ти). Consonant doubling marks both a long sound (життя́, ні́ччю) and morpheme boundaries (відда́ти, беззву́чний) — meaningful, not decorative — and unlike Russian, роз-/без-/через- keep з even before voiceless consonants.
- Hard R, Hard Labials, and the Apostrophe SoundB1 — Ukrainian р and the labials б п в м ф stay HARD before я/ю/є/ї — which is exactly why the apostrophe exists: м’ясо is /ˈmjɑso/ (hard м + /j/ + vowel), not a Russian-style palatalized /mʲ/. Final р is hard too (лі́кар, тепе́р). The apostrophe means 'hard consonant, full glide'; importing Russian softening here is a clear accent error.
