As Dr Who, was Jon jaunty, just a little? (7)
I believe the answer is:
pertwee
'as dr who was jon' is the definition.
I know nothing about this answer so I can't judge whether this works.
'jaunty just a little?' is the wordplay.
I cannot really see how this works, but
'jaunty' could be 'pert' (I've seen this in another clue) and 'pert' is located in the answer.
'little?' could be 'wee' ('wee' can be similar in meaning to 'little') and 'wee' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pertwee that I've seen before include "'Worzel Gummidge' actor" , "Ex-player" .)
