책이에요 (che-gi-e-yo) – It’s a book

First, listen to the audio below and try to say ‘It’s a book.’ in Korean.

This sentence is made up 책 (book) + 이에요 (is). As you can see, the sentence order in Korean is different to the sentence order in English.

In Korean the verb always comes at the end of the sentence. So, in Korean 책이에요 literally translates as ‘book is‘.

Another important thing to note is that in Korean there is no indefinite article (a/an). So, in English you say ‘It is a book.’, but in Korean there is no need to say ‘a’.

이에요 vs 예요

You may have noticed that in the sentences ‘뭐예요?‘ and ‘책이에요‘ 예요 and 이에요 look and sound very similar.

예요 and 이에요 are the same word and both mean ‘is’ in the sense of ‘is equal to’ in Korean. The one you use depends on whether or not the word that comes before 이에요 / 예요 is a vowel or a consonant.


If the preceding syllable ends in a vowel then 예요 is used. In the question ‘뭐예요?’, 뭐 ends in a vowel (ㅝ) so 예요 is used. This is also the case when answering the question ‘What is it?’ in Korean by saying ‘It is ….’ If the syllable before 예요 / 이에요 ends in a vowel, then 예요 is used.

Here are some examples:

It’s a banana.바나나예요.
It’s an apple.사과예요.
It’s a school.학교예요.
It’s a T-shirt.티셔츠예요.


If the preceding syllable ends in a consonant then 이에요 is used. In the sentence ‘책이에요’, 책 ends in a consonant (ㄱ) so 이에요 is used.

Here are some more examples:

It’s a bag.가방이에요.
It’s a pencil.연필이에요.
It’s a cell phone휴대폰이에요.
It’s water.물이에요.
