Partner grasps computing command (7)
I believe the answer is:
dictate
'command' is the definition.
(I've seen this before)
'partner grasps computing' is the wordplay.
'partner' becomes 'date'.
'grasps' is an insertion indicator.
'computing' becomes 'ICT' (Information and Communications Technology).
'date' placed around 'ict' is 'DICTATE'.
(Other definitions for dictate that I've seen before include "Issue commands" , "speak slowly" , "Give orders like Stalin" , "Command" , "Lay down the law" .)
