Liberal not present - that's handy (2,3)
I believe the answer is:
of use
'handy' is the definition.
(I've seen this before)
'liberal not present' is the wordplay.
I cannot really understand how this works, but
'not' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
The remaining letters 'fuse' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for of use that I've seen before include "Employable" , "Having a function" , "Helpful" , "Nifty" , "Useful" .)
