Our language is very beautiful, and one of the reasons is euphony in Ukrainian. In this article, find out how to use У vs В, І vs Й, and З vs ЗІ vs ІЗ in Ukrainian.

What is euphony in Ukrainian?

euphony in Ukrainian

Ukrainian is one of few languages that have their own natural ways of sounding good. These include a large number of vowels, soft consonants, and simplification of sounds. If you want to sound as beautifully as native speakers, you have to remember the rules of euphony – правила милозвучності.

Милозвучність – “nice sounding” or euphony means avoiding too many consonants or vowels in a row. So, what are the rules of euphony in Ukrainian

What do у / в, і / й, з / зі / із mean?

Here is the basic translation of these short words:

  • Both у and в mean in, at.
  • Both i and й are variants of and
  • З, із and зі are translated as with or from

Be aware that these are the basic meanings. They may change depending on the words around them. Well, see for yourself!

Alternation у-в, і-й

ConsonantУ / Іconsonant

This is clear: to avoid consonants piling up, add a vowel.

  • Я ж тільки заглянув у телефон, перевірив інстаграм і фейсбук.
    I have just looked into my phone, checked Instagram and Facebook.

VowelВ / Йvowel 

Obviously, there should not be too many vowels as well. 

  • На вечерю в Андрія курка й омлет.
    Andrew has chicken and omelet for dinner.

VowelУ в, ф, льв, св., тв., зв

All of the abovementioned consonant collocations (льв, св, тв, etc.) sound similar to в, that is why we use у to achieve euphony in Ukrainian.

  • Гарно у Франківську!
    It is beautiful in Frankivsk!

VowelВconsonant (except for в, ф, льв, св., тв., зв)

When there is both a consonant and a vowel, go for в in the sentence.

  • Поїхали в Канаду!
    Let’s go to Canada! 

Ія, ю, є, ї, й

Pay attention: й is one consonant [j], but the letters я, ю, є, ї represent two sounds [ja], [ju], [je], [ji], a consonant and a vowel, at the same time. 

  • Федір і його дівчина люблять дивитися “Друзів” і їсти.
    Fedir and his girlfriend like watching Friends while eating. 

І between contrasting concepts

Remember to say і between opposites:

  • Злочин і кара
    Crime and Punishment
  • він і вона
    he and she

Alterations in words

Warning: this information might blow your mind! The alternation у-в, і-й happens in some words. It does not change their meaning but helps to achieve euphony in Ukrainian. Remember:

  • учитель – вчитель
  • вже – уже
  • учора – вчора
  • імовірно – ймовірно
  • іти – йти

Moreover, there are words that change meaning depending on the first sound – у or в. Know the difference:

  • вправа й управа
    exercise and control
  • вдача й удача
    character and luck
  • вступ і уступ
    entering and ledge
  • вклад і уклад
    contribution and structure

Alternation з-зі-із

Teacher: Is it з, із or зі? – Me: 


Just like with В, to avoid vowels piling up, add a consonant.

  • Ми повернулися з автомайстерні.
    We came from a garage.


Even when you have one consonant, still choose З.

  • Євген прийшов з Анною.
    Yevhen came with Anna.


Basically, it is the same rule.

  • Ми з тобою – однієї крові.
    You and I are the same blood.

Consonant ІЗconsonant

Remember to add a vowel in between two consonants.

  • Я родом із Китаю.
    I am originally from China.

ІЗ in front of с, ш

To avoid too many similar sounds, use ІЗ in front of hissing sounds.

  • Пані із собачкою.
    A lady with a dog.
  • Шарф із шапкою.
    A scarf with a hat.

ЗІ in front of consonants з, с, ш, щ + consonant

Using a few similar consonants in a row does not sound very nice. It is a good idea to add a vowel to the mix:

  • зі страху
    out of fear
  • зі студентської бібліотеки
    out of a students library

Watch out! There are two expressions to remember:

  • зі мною
    with me
  • зі Львова
    from Lviv

Дякую, що ти завжди зі мною. Thank you for always standing by me.

Euphony in Ukrainian: rule of thumb

At the end of the day, the remarkably euphonic Ukrainian is not that hard: just do not forget to alternate vowel and consonant sounds and you will be fine (in most cases 🙂 ) 

To be honest, Ukrainians often break those euphony rules when speaking ― we just go for what sounds best to us in the moment.
