Hello 좋아 means "to be good" 좋아해 means "to like" However, they could be used interchangeably as the meaning is similar. The only difference is when you use particles Adding the particle 가/이 너가 좋아 = this is correct 너가 좋아해 = this doesn't make sense Adding the particle 를/을 너를 좋아 (doesn't make sense) 너를 좋아해 = this is correct Other examples 이게 좋아 = this is good! 나는 이거를 좋아해 = I like this Actually, both sentences could be interpreted as "I like this" so actually you don't have to worry about which one to use unless you are using particles Hope this helps^^

Thanks!

When you have a positive idea about a subject or object then for expressing your approval about that thing you'll use (좋아) and when you like something or someone (mind you, this feeling of like doesn't mean love, it just means having a pleasant feeling about something or someone) then you will use (좋아해). ---> 좋아: 이 책을 좋아 . ( This book is good.) ---> 좋아해: 나는 컴표터 게음을 좋아해요. ( I like computer game.), 나는 너를 좋아해. ( I like you. )
