Untaxed turnover over the quarter has neglected the odd occupation (6)
I believe the answer is:
tenure
'occupation' is the definition.
(I've seen this before)
'untaxed turnover over the quarter has neglected the odd' is the wordplay.
I cannot quite understand how this works, but
'over' could be 're' and 're' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'quarter' could be 'n' and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tenure that I've seen before include "Residence" , "Incumbency" , "The holding of office or land" , "Permanent employment right" , "Right to keep job" .)
