Kaccāyana, its thirteenth-century recast and its fourteenth-century primer, translated in one consistent style, with every later rule linked to the Kaccāyana sutta it is.

Kaccāyana is the earliest surviving Pāli grammar, traditionally ascribed to the Buddha’s disciple Mahākaccāyana and compiled around the sixth or seventh century CE. Two later works of its school are translated alongside it: Buddhappiya’s Padarūpasiddhi (thirteenth century), which recasts its rules in a teaching order with full paradigms and the derivation of every form, and Dhammakitti’s Bālāvatāra (fourteenth century), the primer for beginners that abridges both. The three texts are translated in one style and cross-referenced rule by rule, so that a Kaccāyana sutta, Buddhappiya’s treatment of it and Dhammakitti’s abridgement are always a click apart.

Modern terminology
The grammar is described in its own terms, in modern natural English: inflection forms ①…⑦ with ⨀ singular and ⨂ plural rather than Latin cases and declensions, and every technical term kept in Pāli and explained.
Optionality as the tradition read it
Every vā, kvaci, navā and vibhāsā is analysed after Aleix Ruiz-Falqués’ account of the two levels of optionality: an open option, or one restricted to a stated domain.
Worked examples
Every example is derived step by step, rule by rule, and its Tipiṭaka source is cited and linked to tipitaka2500.github.io; counter-examples explain what a rule does not do.
Cross-checked
The translations are collated against the earlier English translations reproduced here: Nandisena (done), Malai (in progress) and the 1935 Calcutta Bālāvatāra (to follow).
Structure made visible
Diagrams of the kinds of rule, maps of each text onto Kaccāyana’s chapters, decision charts for sandhi, and taxonomies of compounds, suffixes and model nouns.
