Drunk Ray jailed by explosive oppressor (6)
I believe the answer is:
tyrant
'oppressor' is the definition.
(I've seen this before)
'drunk ray jailed by explosive' is the wordplay.
I cannot really understand how this works, but
an anagram of 'ray' is 'yra' which is present in the answer.
'explosive' could be 'tnt' (TNT is an example) and 'tnt' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tyrant that I've seen before include "Despotic ruler" , "Autocrat - bully" , "Harsh and absolute ruler" , "Oppressor" , "Oppressive and cruel ruler" .)
