indeclinable particle
Etymology. From *bhe-yā, combining the copular root *bher- (be, become) with the emphatic suffix -yā; cognate with Greek phe- (in phēmi "say, assert"), Latin for "were" (past tense of esse), and English be. The form emphasizes assertion or confirmation through its verbal ancestry.
