Endless profession of pulpiteer, laying it on with a trowel? (7)
I believe the answer is:
impasto
'endless profession' is the definition.
The definition suggests a singular noun which matches the answer.
'of pulpiteer laying it on with a trowel?' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
'a' is within the answer.
The remaining letters 'imps' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for impasto that I've seen before include "Method of painting" , "artistic technique" , "Thickly-applied painting technique" , "Style of painting" , "Technique of paint applied thickly" .)
