One who painted over second entrance (7)
I believe the answer is:
ingress
'entrance' is the definition.
(synonyms)
'one who painted over second' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'over' could be 're' and 're' is found in the answer.
'second' could be 's' (common abbreviation) and 's' is found within the answer.
The remaining letters 'ngs' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ingress that I've seen before include "Singers (anag.)" , "Ribbon-like pasta" , "Means of access" , "Way in" , "coming in" .)
