Can writer provide pleasant solution? (7)
I believe the answer is:
amiable
'provide pleasant solution?' is the definition.
I can't tell whether this definition defines the answer.
'can writer' is the wordplay.
I cannot really see how this works, but
'can' could be 'able' (I've seen this in other clues) and 'able' is found within the answer.
'writer' could be 'i' (the person who is writing these clues) and 'i' is present in the answer.
The remaining letters 'am' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for amiable that I've seen before include "Friendly and good-natured (7)" , "Friendly, kindly" , "Good-humoured" , "'Friendly, pleasant and good-tempered (7)'" , "'Cordial, friendly (7)'" .)
