Apathetic trade union relaxed ahout conclusion of action (12)
I believe the answer is:
uninterested
'apathetic' is the definition.
(similar in meaning)
'trade union relaxed ahout conclusion of action' is the wordplay.
I cannot really see how this works, but
'union' could be 'u' (common abbreviation as in Trades Union Congress) and 'u' is located in the answer.
'relaxed' could be 'rested' (I've seen this before) and 'rested' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for uninterested that I've seen before include "indifferent" , "Apathetic" , "Bored" , "Not concerned" .)
