Peer and knight, stuck in bathrooms, regularly vexed (4-3)
I believe the answer is:
look-see
'peer' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I don't see?
'knight stuck in bathrooms regularly vexed' is the wordplay.
'knight' becomes 'k'.
'stuck in' is an insertion indicator.
'bathrooms' becomes 'loos' (loo is a kind of bathroom).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'vexed' are 'ee'.
'k' inserted within 'loos' is 'looks'.
'looks'+'ee'='LOOK-SEE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for look-see that I've seen before include "Dekko" , "Survey, inspection" , "Young's - relates stress and strain (Physics)" , "Inspection (colloq.)" , "Brief inspection" .)
