Ignorant of Stubbs's pottery work? (7)
I believe the answer is:
'ignorant of' is the definition.
(not aware of something)
'stubbs's pottery work?' is the wordplay.
I cannot quite understand how this works, but
'pottery' could be 'ware' (I've seen this before) and 'ware' is found within the answer.
'stubbs' could be 'una' (actress Una Stubbs is an example) and 'una' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for unaware that I've seen before include "Not knowing (of a situation or fact)" , "Innocent" , "Unexpected" , "Ignorant - unconscious" , "Not conscious of what is going on" .)
