Henry getting on in government farm (7)
I believe the answer is:
holding
'farm' is the definition.
(thesaurus)
'henry getting on in government' is the wordplay.
'henry' becomes 'h' ('H' can be a synonym of 'henry').
'getting on' becomes 'old' ('getting on a bit' means 'old').
'government' becomes 'g'.
'h'+'old'+'in'+'g'='HOLDING'
(Other definitions for holding that I've seen before include "Piece of leased land, often small" , "-- Company; -- pattern" , "Long hid (anag.)" , "Farm; stacking (of aircraft waiting to land)" , "Something owned" .)
