Expert flyer to trap rook and land (4)
I believe the answer is:
acre
'land' is the definition.
(I've seen this before)
'expert flyer to trap rook' is the wordplay.
I cannot really understand how this works, but
'rook' could be 'r' (chess abbreviation) and 'r' is located in the answer.
'expert' could be 'ace' (ace can informally mean very good) and 'ace' is found in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for acre that I've seen before include "Race (anag.)" , "Four roods - Israeli port" , "Area measure - Israeli port - Brazilian state" , "Care about the piece of land" , "Mediterranean port" .)
