Office for large man in California (8)
I believe the answer is:
clerical
'office' is the definition.
(I've seen this before)
'large man in california' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'man' becomes 'eric' (I've seen this before).
'in' means one lot of letters goes inside another.
'california' becomes 'cal' (short for California).
'l'+'eric'='leric'
'leric' placed within 'cal' is 'CLERICAL'.
'for' is the link.
(Other definitions for clerical that I've seen before include "kind of error" , "Of office work or church ministers" , "Relating to the priesthood or office work" , "Call Eric, being of the priesthood" , "working in an office" .)
