an Indian word in very common use, means real, bona fide; as, He is a commander, but not a pucka one (i.e. not officially appointed, but only acting as such, pro tempore). The queen reigns, but her ministers are the pucka rulers. A suffragan bishop, an honorary canon, a Lynch-judge, a lieutenant-colonel, the temporary editor of a journal, are not pucka, or bona fide so.
