Usual male in charge beginning to doubt (10)
I believe the answer is:
accustomed
'usual' is the definition.
(I've seen this before)
'male in charge beginning to doubt' is the wordplay.
I cannot quite see how this works, but
'male' could be 'tom' (tom can mean a male cat) and 'tom' is present in the answer.
'charge' could be 'accuse' (charge in court) and 'accuse' is located in the remaining letters.
A single letter 'd' remains 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 accustomed that I've seen before include "familiar" , "Used to" , "usual" .)
