Apparent, seeming (10)
I believe the answer is:
ostensible
I believe this clue is a double definition.
'apparent' is the first definition.
(synonyms)
'seeming' is the second definition.
(synonyms)
(Other definitions for ostensible that I've seen before include "Manifest" , "Supposed" , "Apparently true" , "Apparent" , "Professed" .)
