Give the lip a decent trim where the chopper lands (7)
I believe the answer is:
helipad
'where the chopper lands' is the definition.
The definition suggests a singular noun which matches the answer.
'give the lip a decent trim' is the wordplay.
'trim' indicates a hidden word (I've seen 'trimmed' mean this (part of the clue must be trimmed away)).
'HELIPAD' can be found hidden inside 'give the lip a decent'.
Can you help me to learn more?
(Other definitions for helipad that I've seen before include "Landing place for one type of aircraft" , "Reception area for travellers" , "Where chopper lands" , "chopper came down" , "Area for choppers to take off and land" .)
