Unsuitable confession from person who nods off before time (5)
I believe the answer is:
inapt
'unsuitable' is the definition.
(I've seen this before)
'confession from person who nods off before time' is the wordplay.
I cannot really understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found in the answer.
'time' could be 't' (abbreviation) and 't' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for inapt that I've seen before include "not fit for purpose" , "Useless" , "Ill-suited" , "Not suitable or appropriate" , "Free from deceit" .)
