Amenable and upright character engaged by factory (6)
I believe the answer is:
pliant
'amenable' is the definition.
(thesaurus)
'upright character engaged by factory' is the wordplay.
'upright character' becomes 'I' (vertical letter of the alphabet).
'engaged by' indicates putting letters inside (I've seen this in other clues).
'factory' becomes 'plant' (I've seen this in another clue).
'i' going inside 'plant' is 'PLIANT'.
'and' acts as a link.
(Other definitions for pliant that I've seen before include "Adaptable" , "Flexible, easily bent or influenced" , "Flexible and easily manipulated" , "Bendable" , "Not firm" .)
