Turn over lids to see it (4)
I believe the answer is:
spot
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'turn over lids' is the wordplay.
'turn over' is a reversal indicator.
'lids' becomes 'tops' (I've seen this in another clue).
'tops' backwards is 'SPOT'.
'to see' is the link.
Can you help me to learn more?
(Other definitions for spot that I've seen before include "Informally, catch sight of" , "See; location" , "moral flaw" , "Predicament" , "Detect" .)
