Having detected one's weak point, nagged about it (5,5)
I believe the answer is:
found fault
'having' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'detected one's weak point nagged about it' is the wordplay.
I cannot really understand how this works, but
'detected' could be 'found' ('find' can be a synonym of 'detect') and 'found' is found within the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
The remaining letters 'ful' 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?
