Support software program and move over (7)
I believe the answer is:
approve
'support' is the definition.
(I know this)
'software program and move over' is the wordplay.
'software program' becomes 'app' (I've seen this before).
'and' says to put letters next to each other.
'move' is an anagram indicator (I've seen 'moved' mean this).
'over' anagrammed gives 'rove'.
'app'+'rove'='APPROVE'
(Other definitions for approve that I've seen before include "Pronounce (something) satisfactory" , "Consider right" , "Say yes to" , "Think highly of - sanction" , "Think well of; sanction" .)
