Is he an artisan of some depth? (7)
I believe the answer is:
plumber
'artisan of some depth?' is the definition.
'plumber' can be an answer for 'artisan' (plumber is a kind of artisan). I am unsure of the 'of some depth?' bit.
'is he an' is the wordplay.
I cannot quite see how this works, but
'is' could be 'be' and 'be' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for plumber that I've seen before include "One fits water and gas pipes" , "domestic technician" , "tank specialist?" , "Repairer of pipes" , "One instals and repairs water and gas fittings" .)
