Anything said to take less than a fortnight (5)
I believe the answer is:
aught
'anything' is the definition.
(I've seen this before)
'said to take less than a fortnight' is the wordplay.
I cannot really see how this works, but
'said' could be 't' (I've seen this in other clues) and 't' is present in the answer.
'a' is found in the answer.
The remaining letters 'ugh' is a valid word 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 aught that I've seen before include "Anything at all (archaic)" , "Emphatically anything" , "Anything (Shakespearean)" , "Nothing" .)
