Consider female donkey? (6)
I believe the answer is:
assess
'consider' is the definition.
(thesaurus)
'female donkey?' is the wordplay.
I cannot quite understand how this works, but
'donkey?' could be 'ass' (ass is a term for a donkey) and 'ass' is found within the answer.
The remaining letters 'ess' 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 assess that I've seen before include "Place a value on" , "Estimate, gauge" , "'Judge, estimate (6)'" , "Estimate the worth or quality of" , "Evaluate (quality)" .)
