Put new items in official data gathering processes (5)
I believe the answer is:
refit
'put new items' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'official data gathering processes' is the wordplay.
I cannot really understand how this works, but
'official' could be 'ref' (match official in football, say) and 'ref' is present in the answer.
The remaining letters 'it' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for refit that I've seen before include "provision of new equipment" , "Equip by repairing or replacing parts" , "Do repair job" , "Restoration and repair of equipment etc" , "Renovate (a ship)" .)
