An Arab craft? Yes, certainly! (3,3)
I believe the answer is:
and how
'certainly' is the definition.
(I've seen this before)
'an arab craft? yes' is the wordplay.
I cannot quite understand how this works, but
'an' could be 'a' and 'a' is found in the answer.
'craft?' could be 'dhow' (dhow is a kind of craft) and 'dhow' is present in the answer.
A single letter 'n' 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 and how that I've seen is " Certainly".)
