Clothes for undercover agent whir strangely? (9)
I believe the answer is:
nightwear
'clothes' is the definition.
(nightwear is a kind of clothes)
'agent whir strangely?' is the wordplay.
'strangely?' is an anagram indicator (I've seen 'strangely' mean this).
'agent'+'whir'='agentwhir'
'agentwhir' is an anagram of 'NIGHTWEAR'.
'for undercover' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for nightwear that I've seen before include "Pyjamas e.g." , "What's on after the watershed" , "Bedroom items" , "Clobber after hours" , "evening dress" .)
