Pali classical grammars reflect a specific idea of what Pali Buddhist texts are. According to this traditional idea, texts are mainly conceived as sound and therefore the initial portions of every grammar deal with sound and sound ligature or sandhi. Sandhi in Pali does not work as systematically as it does in Sanskrit and therefore Pali grammarians have struggled with the optionality of many of their rules on sound ligature. Unlike modern linguists, however, they identify certain patterns of fixed or (...) frozen sandhis that are often associated to the formulas of Pali prose. This paper focuses on these specific frozen sandhis in Pali prose and their connection to the nature of Pali literature broadly. The main working hypothesis is the following: in the same way that certain frozen sandhis in verse obey metrical patterns, frozen sandhis in prose suggest that Pali speech-sounds are subordinated to formulaic rhythmic structures.
