I believe the answer is:
'feigned' is the definition.
('pretend' can be a synonym of 'feign')
This is all the clue.
(Other definitions for pretended that I've seen before include "Feigned, affected" , "Made believe, feigned," , "Feigned, faked" , "Made believe with intent to deceive" , "Engaged in fantasy; simulated (an emotion)" .)
