Every language remodels the words it borrows, but Ukrainian does it with unusually firm rules. When an international term like system, discipline, or rhythm enters Ukrainian, it is not transcribed letter-for-letter — it is rebuilt to obey Ukrainian spelling and pronunciation, and the single rule that governs that rebuild for hundreds of words is the дев’ятка ("the nine"). Add to that a handful of conventions for foreign g, h, w and th, plus the fact that Ukrainian refuses to soften or iotate the e in loanwords, and you can predict the Ukrainian form of an international word — and read it aloud correctly — far more reliably than you might expect. This page is about that predictability. It builds on the г/ґ distinction and the и vs і contrast, so have those in mind.
The дев’ятка rule: и after nine consonants
Here is the most-tested orthography point in the whole loanword system. In common loanwords (загальні назви — everyday international vocabulary, not exotic proper names), you write и, not і, when an /i/ sound comes after one of nine consonants and before another consonant. The nine consonants are:
д, т, з, с, ц, ч, ш, ж, р
A traditional mnemonic packs all nine into one nonsense phrase that Ukrainian schoolchildren memorise: «Де ти з’їси цю чашу жиру?» ("Where will you eat this bowl of fat?") — the initial consonants of those words are д-т-з-с-ц-ч-ш-ж-р, exactly the nine.
This is not just a spelling convention — it is a pronunciation rule too. The и in these words is the genuine Ukrainian central /ɪ/ (the vowel of "bit"), distinct from the front /i/ of і. So you both write and say и.
дисциплі́на
discipline — д before и, ц before и: both follow the дев’ятка (after д and ц, before a consonant). Said with the central и, not 'ee'.
систе́ма
system — с + и (after с, before с): дев’ятка. Not ‘сістема’.
ритм
rhythm — р + и (after р, before т): дев’ятка. The /i/ of English 'rhythm' becomes Ukrainian и.
цисте́рна
tank / cistern — ц + и (after ц), with с + е kept as a plain 'e': two loanword rules in one word.
When you keep і instead
The rule has firm edges. You write і (not и) whenever the /i/ sound is not in that exact environment — that is, after a consonant outside the nine, or at the start of a word, or before a vowel, or at the end of a word.
хі́мія
chemistry — х is NOT one of the nine, so і stays: хі-мі-я. (Also, the second і is before a vowel.)
літерату́ра
literature — л is not one of the nine, so і: лі-те-ра-ту-ра. The т that follows would trigger и only if т came BEFORE the і.
ра́діо
radio — here і comes before a vowel (о), so the дев’ятка does not apply: ра-ді-о, written with і even though р is one of the nine.
The last example shows the trap clearly: р is one of the nine, but и is required only before a consonant. Before the vowel о, you revert to і. The full environment is: one of the nine consonants + і-sound + another consonant. Miss any of the three conditions and і returns.
Foreign g, h, w and th
Beyond vowels, loanwords force decisions about consonants that Ukrainian doesn't natively have in the foreign position.
Latin/Greek g → г (mostly)
The default for foreign g is the Ukrainian г — the breathy voiced /ɦ/, not the hard ґ. This is why a "geologist" is a геоло́г and a "newspaper" (from Italian gazzetta) is газе́та. In some newer borrowings, especially brand names and recent technical terms, ґ (the hard /g/) is gaining ground, but the traditional, safe rendering of historic loanwords is г.
геоло́г
geologist — Latin/Greek g rendered as Ukrainian г (the breathy /ɦ/), not ґ: 'heoLÓH'.
газе́та
newspaper — from Italian gazzetta; the g becomes г: 'haZÉta', not ‘ґазета’.
Foreign h → г (this is the crucial one)
Here is the point that trips up English speakers most. English h is rendered by Ukrainian г, not ґ. The logic is sound once you hear it: Ukrainian г is itself a voiced h-like fricative /ɦ/, so it is the natural match for an English or German h. "Harvard" is Гарвард; "hotel" is готель; "hobby" is гобі.
Га́рвард
Harvard — English initial h rendered as Ukrainian г: 'HÁRvard', NOT ‘Ґарвард’.
готе́ль
hotel — English/French h → г, with the soft л marked by ь: 'hoTÉL''. Not ‘ґотель’.
Гельсі́нкі
Helsinki — h → г again; note і kept after л and after н (л and н are not in the дев’ятка).
English w → в
English w (Washington, weekend, Wales) is rendered with в, pronounced as the Ukrainian labial /w/~/v/.
Вашингто́н
Washington — w → в, and note ш + и (дев’ятка: ш is one of the nine, before н): 'vaShynHTÓN'.
th → т or с
English th has no Ukrainian sound, so it is approximated — historically often as т (Greek-derived theta words) and sometimes as с. "Theatre" came through as теа́тр (т); "thriller" is три́лер (т).
теа́тр
theatre — Greek th rendered as т: 'teÁTR‘. The е stays a plain ’e'.
Foreign е is never iotated
A reflex English and Russian speakers must suppress: in loanwords, Ukrainian е stays a plain, hard /e/. It does not become "ye" and it does not soften the preceding consonant the way native-feeling spelling might suggest. "Test" is тест (hard т, plain е), "metro" is метро́, "tennis" is те́ніс. The vowel /i/ in loanwords, meanwhile, is carried by і (or ї after a vowel), never by и unless the дев’ятка forces it.
тест
test — plain hard т + plain е: 'test', exactly as English. The е does NOT soften the т.
метро́
metro / underground — ме-ТРО́, hard е throughout, stress on the final syllable as in French.
ме́неджер
manager — every е is a plain hard 'e'; the soft-sounding English vowels are flattened to Ukrainian е.
Stress: usually inherited, sometimes shifted
Loanwords tend to keep the stress of the source language — which is itself useful, because it means a French word stresses its last syllable (метро́, бюро́), a word from English often keeps its English stress, and a Greek/Latin word keeps the classical placement. But Ukrainian sometimes shifts the stress to fit its own rhythm, and there is no fully mechanical rule — when in doubt, check the dictionary.
бюро́
bureau / office — French final stress preserved: 'byuRÓ'.
кіломе́тр
kilometre — stress on -ме-, the Ukrainian/European placement (contrast English 'KILometre').
Source-language comparison: what English and Russian speakers must adjust
For an English speaker, the hardest reflex to drop is reading the Latin letters of the loanword and pronouncing the English vowels. систе́ма is not "sis-TEE-ma"; it is "sys-TÉ-ma" with the central и and a plain е. And the h-words feel wrong at first: saying "Гарвард" for Harvard with a breathy г, not a hard g, takes practice.
For a Russian-trained speaker, the trap is different. Russian renders many of these same loanwords with и too, but Russian h often goes to х or г inconsistently (Гарвард but Хельсинки), whereas Ukrainian is more uniformly г for foreign h. And Russian has no separate ґ to even tempt you — but Ukrainian does, and the temptation to "upgrade" foreign g/h to the hard ґ must be resisted for classic vocabulary.
Common Mistakes
❌ дисціпліна
Incorrect — after д and ц (both in the дев’ятка), before a consonant, you must write и: дисципліна.
✅ дисциплі́на
discipline — д + и, ц + и by the дев’ятка rule.
❌ Ґарвард / ґотель
Incorrect — foreign h is rendered by Ukrainian г, not the hard ґ.
✅ Га́рвард, готе́ль
Harvard, hotel — English h → г.
❌ сістема, рітм
Incorrect — с and р are in the дев’ятка; before a consonant the /i/ must be и: система, ритм.
✅ систе́ма, ритм
system, rhythm — и after с and after р.
❌ хи́мія, литерату́ра
Incorrect — х and л are NOT in the дев’ятка, so the /i/ stays і: хімія, література.
✅ хі́мія, літерату́ра
chemistry, literature — і after consonants outside the nine.
❌ ра́дио (и before the vowel о)
Incorrect — the і here comes before a vowel (о), so the дев’ятка does not apply even though р is one of the nine: радіо.
✅ ра́діо
radio — і kept because the next sound is a vowel, not a consonant.
Key Takeaways
- The дев’ятка rule writes (and says) и after д т з с ц ч ш ж р when an /i/ sound stands before a consonant in a loanword: дисципліна, система, ритм, цистерна.
- Break any condition — consonant outside the nine, /i/ before a vowel or at word edge — and you revert to і: хімія, література, радіо.
- Foreign g usually → г (газета, геолог); foreign h also → г (Гарвард, готель), not the hard ґ — this is the norm for classic loanwords.
- English w → в (Вашингтон); th → т/с (театр).
- Loanword е stays a plain hard /e/ — it never iotates or softens (тест, метро).
- Stress usually follows the source language but can shift; when unsure, check the dictionary.

- The Sound of Г (/ɦ/)A2 — Ukrainian г is a voiced glottal/pharyngeal fricative /ɦ/ — a breathy, throaty, VOICED 'h' (like the h in 'aha'), never the hard /g/ of 'go.' The hard /g/ is the separate letter ґ. Mastering this one sound transforms a Ukrainian accent.
- The Дев'ятка Rule and Spelling LoanwordsB1 — The «правило дев’ятки» (rule of nine) is the master rule for и vs і in borrowings: after the nine consonants д т з с ц ч ш ж р, write и (not і) when the next letter is a consonant — систе́ма, ри́тм, дисциплі́на, ци́рк. After every other consonant, and before a vowel, ь, or apostrophe, write і/ї — хі́мія, кіно́, бі́знес, ра́діо. One rule decides the spelling of hundreds of international words.
- І, И, and Ї: The Three i-SoundsA1 — The trio і / и / ї is the feature English learners — and Russian-trained learners especially — get wrong most: і = /i/ (a clear 'ee' that softens the consonant before it), и = /ɪ/ (the hard central 'bit' vowel that does not soften), and ї = /ji/ (always iotated, never after a consonant).
- When to Write І vs ИA2 — The orthography rules that decide і vs и — a top spelling challenge because in loanwords the two letters become hard to choose. NATIVE words: и never begins a word (use і: і́м’я, і́нший), and і/и are distinct sounds you can usually hear (ри́ба has и, ліс has і). LOANWORDS: the дев’я́тка rule — write и (not і) after the nine consonants д т з с ц ч ш ж р when a consonant follows in common borrowings (систе́ма, дире́ктор, ритм), but і elsewhere and after other consonants (хі́мія, кіно́, гіпо́теза). So 'system' is систе́ма (и) and 'chemistry' is хі́мія (і).
