Flees from larks, avoiding flier? (7)
I believe the answer is:
escapes
'flees' is the definition.
(escaping is a kind of fleeing)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for escapes that I've seen before include "Gets free" , "breaks out,gets away" , "Flights" , "Gets away from captivity" , "Breaks out, gets away" .)
