Recognise Chinese porcelain appearing (7)
I believe the answer is:
seeming
'appearing' is the definition.
('seem' can be a synonym of 'appear')
'recognise chinese porcelain' is the wordplay.
'recognise' becomes 'see' (I've seen this before).
'chinese porcelain' becomes 'ming' (I've seen this before).
'see'+'ming'='SEEMING'
(Other definitions for seeming that I've seen before include "Apparent" , "Specious" , "Appearing as such, but not necessarily so" , "so-called" , "Ostensible" .)
