Flier possibly born to get out of line? (5)
I believe the answer is:
robin
'flier' is the definition.
(robin is a kind of birdanimal)
'possibly born to get out of line?' is the wordplay.
'possibly' is an anagram indicator.
'to get' means one lot of letters goes inside another.
'out of line?' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'born' with letters rearranged gives 'robn'.
'robn' going around 'i' is 'ROBIN'.
Can you help me to learn more?
(Other definitions for robin that I've seen before include "See 7" , "Garden bird" , "See 12" , "Red-breasted songbird" , "flier" .)
