Handyman in particular old corporation (8)
I believe the answer is:
factotum
'handyman' is the definition.
(I've seen this before)
'particular old corporation' is the wordplay.
'particular' becomes 'fact' (I am not sure about this - if you are sure you should believe this answer much more).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'corporation' becomes 'tum' ('corporation' is a humorous term for stomach fat).
'fact'+'o'+'tum'='FACTOTUM'
'in' is the link.
Can you help me to learn more?
(Other definitions for factotum that I've seen before include "Versatile employee" , "Assistant doing all kinds of work" , "Jack of all Trades" , "One employed to do various jobs" , "Odd-job servant" .)
