Assume old temple can be made out (5)
I believe the answer is:
feign
'assume' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for feign that I've seen before include "Pretend, create false impression" , "Pretend, put on show of" , "Pretend to experience" , "Pretend, simulate" , "Pretend to be affected by" .)
