Definition: denotation of two or more things by one single member by virtue of their being put together in a dvandva compound of two or more words; the grammarians advocate this doctrine stating that in a dvandva compound such as घटपटौ or घटपटम्, the word घट has the capacity of expressing the sense of both घट and पट, which in a sentence घटः पटश्च, it does not possess. Similarly पट also has the capacity of conveying the sense of both पट and घट. Possibly this theory is advocated by grarnmarians, on the analogy of words like पितरौ or मातरौ for मातापितरौ, द्यावा for द्यावापृथिवी and so on; cf. सिद्धं तु युगपदधिकरणवचने द्वन्द्ववचनात् P. II 2.29 Vart. 2. For details see Vyakaranamahabhasya on चार्थे द्वन्द्वः P. II. 2.29.
