Flight attendant to depict aliens in retirement (7)
I believe the answer is:
steward
'flight attendant' is the definition.
(I know that flight attendant is a type of flight attendant)
'depict aliens in retirement' is the wordplay.
'depict' becomes 'draw' (synonyms).
'aliens' becomes 'ETs' (ET is short for extraterrestrial).
'in retirement' says the letters should be written in reverse (retire can mean to go back or backwards).
'draw'+'ets'='drawets'
'drawets' written backwards gives 'STEWARD'.
'to' acts as a link.
(Other definitions for steward that I've seen before include "race course official" , "Ship's waiter" , "bailiff" , "Flight attendant" , "Waiter; estate manager" .)
