-어 보다

V+ 아/어 보다 This indicates trying something for the first time to gain experience. Mostly written in past tense. (I’ve ~, I tried~ )

한국에 가 봤어요.

I've been to Korea.

(This conveys the experience of having been there, while "한국에 갔어요" simply states a fact.)

TOPIK 시험을 쳐 봤어요.

I've taken the TOPIK exam.

(TOPIK is the official Korean proficiency test. In this example sentence, it sounds as if you took the test more as a casual experience rather than after serious preparation, simply trying it out to see what it was like.)

들어 보세요.

(Try to) listen please.

(Similar to how ‘-어 주세요’ softens the tone of ‘-으세요’, ‘-어 보세요’ is often used to make a command sound less forceful, carrying the nuance of “try doing this action”.)

따라해 보세요.

Repeat please.

• You can regard this form(‘root + 어 보다’) as a single word.

먹어보다 to try(food), to taste
