"An" (안) in Korean means "inside" or "not" (depending on context).

In this sentence, '않' is used to express negation of the verb '가다' (to go). It is a shortened form of '않다', used commonly in conjunction with '것이다' to form the future negated tense.

나는 오늘 학교에 가지 않을 것입니다.

I will not go to school today.

Here, '않다' is used in conjunction with the descriptive verb '달다' (to be sweet) to express negation, meaning this cake does not exhibit excessive sweetness.

이 케이크는 너무 달지 않아요.

This cake is not too sweet.

In this sentence, '않으려고' combines '않다' with the conjunctive ending '-려고', indicating intention or effort to not perform the action '하다' (to do).

거짓말을 하지 않으려고 노력해요.

I am trying not to lie.
