Marionette (6)
I believe the answer is:
puppet
'marionette' is the definition.
(synonyms)
This is all the clue.
(Other definitions for puppet that I've seen before include "Doll controlled by strings" , "Manipulated figure" , "Marionette - poodle" , "eg Sooty; Petrushka" , "It's worked with strings" .)
