Revolutionary task acquiring current home (7)
I believe the answer is:
jacobin
'revolutionary' is the definition.
(I've seen this before)
'task acquiring current home' is the wordplay.
'task' becomes 'job' (synonyms).
'acquiring' indicates putting letters inside.
'current' becomes 'ac' (alternating current).
'home' becomes 'in' ('he's home' can mean 'he's in').
'job' going around 'ac' is 'jacob'.
'jacob'+'in'='JACOBIN'
(Other definitions for jacobin that I've seen before include "French revolutionary" , "What can make one a wild man" , "French radical" , "Extreme radical" , "pigeon" .)
