Familiarise upper class after a while with a veneer of loathing (9)
I believe the answer is:
habituate
'familiarise' is the definition.
(I've seen this in another clue)
'upper class after a while with a veneer of loathing' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'while' could be 'bit' (both can mean an amount of time) and 'bit' is present in the answer.
'upper class' could be 'u' (as in U- and non-U speech) and 'u' is found in the answer.
'loathing' could be 'hate' (loathing is hatred) and 'hate' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for habituate that I've seen is " Get used to".)
