What does 이 do in 책이 재미있어요?

이 is the subject particle. It marks 책 as the subject of the sentence. You attach 이 after a noun that ends in a consonant; if the noun ends in a vowel, you use 가 instead.

Is 재미있어요 a verb or an adjective?

In Korean, descriptive verbs (often called adjectives in English) are verbs that describe states. 재미있어요 comes from 재미있다, which literally combines 재미 (fun) + 있다 (to exist/have). So 재미있다 means “to have fun” → “to be interesting.” The form -어요 is the polite present tense ending for verbs.

Why do people sometimes write 재밌어요 instead of 재미있어요?

재밌어요 is a colloquial contraction of 재미있어요. In casual speech and informal writing, Koreans often drop or shorten syllables for ease. Both forms mean exactly the same thing.

What politeness level is the ending -어요?

The -어요 ending is the standard polite (also called “요-form”) used with strangers, acquaintances, or in most everyday situations.

• More casual: 재미있어 (no 요)
• More formal: 재미있습니다 (formal/official tone)
