Labour beginning to table question (4)
I believe the answer is:
task
'labour' is the definition.
(both can mean a chore)
'beginning to table question' is the wordplay.
'beginning to' suggests taking the first letters.
'question' becomes 'ask' (asking a question).
The first letter of 'table' is 't'.
't'+'ask'='TASK'
(Other definitions for task that I've seen before include "commission" , "Set piece of work" , "Job of work" , "Job, undertaking" , "Assignment" .)
