Is he out to terminate the supply? (5)
I believe the answer is:
peter
'is he' is the definition.
(I've seen this before)
'to terminate the supply?' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
The remaining letters 'peer' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'out' acts as a link.
Can you help me to learn more?
(Other definitions for peter that I've seen before include "Saint at the Pearly Gates?" , "emperor" , "Leading apostle" , "Early Pope" , "Disciple" .)
