句者，攝受諸名究竟，顯了不現見義，故名為句，文者，是顯了義，由文令彼名句呼召諸法分明顯了，以是名句所依處故，亦名為字，不可改轉義名字，可改轉者是名，以隨所詮種種轉變故。

As for 'phrase' (*pada*): because it encompasses names to completion and clearly reveals meanings that are not directly observed, it is called 'phrase.' As for 'phoneme' (*vyañjana*): it has the sense of 'clear revelation'; because phonemes cause those names and phrases to call forth all phenomena distinctly and clearly, and because they are the basis on which names and phrases rely, they are also called 'syllables' (*akṣara*). That which cannot be altered or transformed is called a 'syllable'; that which can be altered or transformed is a 'name,' because it changes in various ways in accordance with what is expressed.
