One providing street with numbers? (6)
I believe the answer is:
busker
'one providing street with numbers?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'one' is the wordplay.
I cannot quite see how this works, but
'one' could be 'er' (I've seen this in other clues) and 'er' is present in the answer.
The remaining letters 'busk' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for busker that I've seen before include "player in street" , "Public entertainer" , "Street musician" , "Street entertainer" , "Street performer" .)
