One who ventures to look around? (5)
I believe the answer is:
scout
'one who ventures to look' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'around?' is the wordplay.
I cannot really see how this works, but
'around?' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
The remaining letters 'scut' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for scout that I've seen before include "Person on the lookout" , "Person sent out to gain information" , "Explore" , "Explorer, spy" , "Soldier on a recce mission" .)
