Meddle in Bury with free movement (9)
I believe the answer is:
interfere
'meddle' is the definition.
(to meddle with something is to interfere with it)
'bury with free movement' is the wordplay.
'bury' becomes 'inter' (to inter is to put into the ground).
'with' means one lot of letters go next to another.
'movement' is an anagram indicator (letters move around).
'free' is an anagram of 'fere'.
'inter'+'fere'='INTERFERE'
'in' is the link.
(Other definitions for interfere that I've seen before include "Meddle, poke into" , "Meddle, butt in" , "Meddle in someone else's business" , "Poke one's nose in" , "Attempt" .)
