 Kātyāyana and Patañjali clearly view words as collections of sounds. Besides using the term “samudāya” for such a collection, they also use the word “varṇasaṃghāta” (“collection of sounds”). They argue that words are built by putting together sounds, and that, while the words are meaningful, the component sounds are not meaningful in themselves. The notion of a word as a collection (saṃghāta) applies not only in the sense that it is a collection of sounds, but also in the sense that complex formations are collections of smaller morphological components.
