Porcelain from French, in alabaster (5)
I believe the answer is:
china
'porcelain' is the definition.
(china is a kind of porcelain)
'from french in alabaster' is the wordplay.
'from' indicates a hidden word.
'CHINA' can be found hidden inside 'french in alabaster'.
(Other definitions for china that I've seen before include "High quality porcelain" , "Land" , "Far Eastern power" , "Ceramic; country" , "Mate (Cockney rhyming slang)" .)
