Sharing Standard piece on which Time article is based (9)
I believe the answer is:
partaking
'sharing' is the definition.
(partaking is a kind of sharing)
'standard piece on which time article is based' is the wordplay.
I cannot really understand how this works, but
'standard' could be 'par' (standard of play in golf) and 'par' is found in the answer.
'piece' could be 'king' (king is a kind of piece) and 'king' is found within the answer.
'time' could be 't' (abbreviation) and 't' is found within the answer.
'article' could be 'a' (the indefinite article in English) and 'a' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
