The sense to compliment a stewardess inside (5)
I believe the answer is:
taste
'the sense' is the definition.
(taste is a kind of sense)
'compliment a stewardess inside' is the wordplay.
'inside' indicates a hidden word.
'TASTE' can be found hidden inside 'compliment a stewardess'.
'to' acts as a link.
(Other definitions for taste that I've seen before include "choice" , "Sensation of flavour" , "Nice distinction felt in the mouth" , "Discrimination - a sense" , "gains experience" .)
