Korean Lesson 이/가 아니에요

Lesson 23: 이/가 아니에요

In this lesson, you will learn how to use the structure 이/가 아니에요 to say things like “It’s not a book.“, “I am not American.”, etc.

Lesson 23: 이/가 아니에요

In lesson 1 of this course, you learned that the ending 예요/이에요 means ‘equal to’ and is used to make sentences like “It’s an apple.“, “I am American.“, etc. 이/가 아니에요 is the negative form of 예요/이에요 and so it is used to make sentences like “It’s not an apple.“, “I am not American.“, etc. Let’s look at some more examples.

책이에요. = It’s a book. ↔ 책이 아니에요. = It’s not a book.
사과예요. = It’s an apple. ↔ 사과가 아니에요. = It’s not an apple.

The structure 이/가 아니에요 is made up of the particle 이/가 plus the present tense form of the adjective 아니다 (to be not). In everyday conversations, 이/가 is often dropped.

Conjugation Rules

When attaching 이/가 아니에요 to a noun you must choose either 아니에요 or 아니에요. The one you choose depends on whether the preceding noun ends in a consonant or vowel. See the table below.
