Finally working as a cobbler, perhaps (6)
I believe the answer is:
atlast
'cobbler perhaps' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'finally working as a' is the wordplay.
I cannot really see how this works, but
'finally' could be 'last' (synonyms) and 'last' is found within the answer.
'a' is found in the answer.
A single letter 't' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for atlast that I've seen is " ultimately".)
