I believe the answer is:

aircraft

I'm a little stuck... Click here to teach me more about this clue!

'flyer' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'look around pile' is the wordplay.
'look' becomes 'air' (something might have a certain air or look).
'around' becomes 'c' (abbreviation for 'circa').
'pile' becomes 'raft' (synonyms).
'air'+'c'+'raft'='AIRCRAFT'

'for' is the link.

Can you help me to learn more?

(Other definitions for aircraft that I've seen before include "Flying transport" , "Flying machine" , "flyers" , "Flying machines" , "Flier" .)
