Utter beast, turning the occupant, Lou, out (8)
I believe the answer is:
absolute
'utter' is the definition.
(similar in meaning)
'beast turning the occupant lou out' 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 found in the answer.
an anagram of 'lou' is 'olu' which is present in the answer.
The remaining letters 'abse' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for absolute that I've seen before include "Total, utter" , "Not subject to limitation" , "Not qualified; total" , "Total; not relative" , "Unconditional, downright," .)
