Friar sat awkwardly, entertaining a revered emperor (3,6)
I believe the answer is:
ras tafari
'revered emperor' is the definition.
'ras tafari' can be an answer for 'emperor' (I've seen this before). I'm not certain of the 'revered' bit.
'friar sat awkwardly entertaining a' is the wordplay.
'awkwardly' indicates anagramming the letters.
'entertaining' means one lot of letters goes inside another (inviting in, as for dinner).
'friar'+'sat'='friarsat'
'friarsat' is an anagram of 'rstafari'.
'rstafari' going around 'a' is 'RAS TAFARI'.
Can you help me to learn more?
(Other definitions for ras tafari that I've seen before include "Movement whose followers worship an Ethiopian emperor" , "Royal once" , "opposed to Babylon?" .)
