Calls up movement to do with words (8)
I believe the answer is:
semantic
'to do with words' is the definition.
(semantic means relating to linguistic meaning)
'calls up movement' is the wordplay.
'calls' becomes 'names' ('name' can be a synonym of 'call').
'up' is a reversal indicator (in down clue: letters go upwards).
'movement' becomes 'tic' (an involuntary physical movement).
'names' written backwards gives 'seman'.
'seman'+'tic'='SEMANTIC'
(Other definitions for semantic that I've seen before include "Of meaning and connotation in language" , "Relating to the meaning of words" , "about what words mean" , "Relating to the study of meaning" , "Tin maces could relate to the meaning of words" .)
