Remit to embrace latitude and freedom of movement (4)
I believe the answer is:
play
'freedom of movement' is the definition.
(as opposed to time spent in a classroom, say)
'remit to embrace latitude' is the wordplay.
'remit' becomes 'pay' (to remit is to send money as payment).
'to embrace' means one lot of letters goes inside another.
'latitude' becomes 'l' (abbreviation for latitude).
'pay' placed around 'l' is 'PLAY'.
'and' acts as a link.
(Other definitions for play that I've seen before include "Drama - latitude - sport" , "Participate in games or sport" , "Theatre production" , "stage production" , "Theatrical production" .)
