Are robins endlessly, recklessly flying? (8)
I believe the answer is:
airborne
'flying?' is the definition.
(I've seen this before)
'are robins endlessly recklessly' is the wordplay.
'endlessly' means to remove the last letter.
'recklessly' indicates anagramming the letters.
'are'+'robins'='arerobins'
'arerobins' with its final letter removed is 'arerobin'.
'arerobin' is an anagram of 'AIRBORNE'.
(Other definitions for airborne that I've seen before include "Aloft, flying" , "so, paras?" , "in Hercules, perhaps" , "(Of aircraft) flying" , "Having taken off" .)
