Beginning to enjoy work in carpeting (6,2,4)
I believe the answer is:
taking to task
'carpeting' is the definition.
Although both the answer and definition are present participle verbs, I don't see how they can define each other.
'beginning to enjoy work in' is the wordplay.
I cannot quite see how this works, but
'to' is within the answer.
'work' could be 'task' (task is a kind of work) and 'task' is present in the answer.
'in' is present in 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 taking to task that I've seen before include "Being a critic" , "beginning to enjoy the job" .)
