The worst possible holes? (4)
I believe the answer is:
pits
'holes?' is the definition.
(pit is a kind of hole)
'the worst possible' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
The remaining letters 'pis' 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).
Can you help me to learn more?
(Other definitions for pits that I've seen before include "Deep holes in the ground" , "Mines" .)
