Temple, dictator's eh? (3)
I believe the answer is:
wat
'temple' is the definition.
(type of Asian temple eg Angkor Wat)
'dictator's eh?' is the wordplay.
'dictator's' indicates a 'sounds like' (homophone) clue (as somebody dictating would pronounce the word).
'eh?' becomes 'what' ('eh' can mean 'pardon' or 'what').
'what' sounds like 'WAT'.
(Other definitions for wat that I've seen before include "Rebel" , "having had a wee drap too much?" , "Buddhist temple" .)
