Pick up a bit on movement (6)
I believe the answer is:
obtain
'pick up' is the definition.
(thesaurus)
'a bit on movement' is the wordplay.
'movement' indicates an anagram.
'a'+'bit'+'on'='abiton'
'abiton' anagrammed gives 'OBTAIN'.
(Other definitions for obtain that I've seen before include "Gain possession of" , "Acquire, secure" , "Come into possession of" , "Get, procure" , "Get - secure" .)
