Thank you very much!!!!!!:)

Think about the difference between 'to recall' and 'to remember'. 기억하다, 기억나다 are quite similar but a little bit different, like them. You can say, '어릴 적 기억나는 별명 없나요? 어릴 적 별명중 기억하는 것 있나요? 기억하는 어릴 적 별명 있나요? But 어릴 적 기억하는 별명...the nickname which you can remember when you were a child...

Oh!!!! Thank you so much!!! I se...I have a mistake... I thought this word is 기억하다, but now I se... is this 기억나다? Am I right? But, please...1 more thing... can you explain the different between 기억하다 and 기억나다 ? Or...can I use in this sentence 기억하다 ? :)

in korean , just like in english there is a need to describe detailed information about a subject or an object. In english we do it with a clause (whom, which, who, that + whatever information you supply in the clause). In korean it is done with a modifying structure you have pointed out. That portion in (1) means "the nickname that I could remember"--> the verb + 는 + noun. (2) comes from 없다 which is "It does not exist" with 나요 it is probably posed as an interrogation (not necessarily direct to a third person. could be a self-interrogative style)--> does it not exist? (3) 적 is similar to 때 which means "the time when"
