This module contains new entry creation rules for පුරාතන ග්‍රීක; see WT:ACCEL for an overview, and Module:accel for information on creating new rules.


-- To do: add dialect labels, at least for non-Attic dialects.
-- Ideally, dialectal lemmas and non-lemma forms should be in different
-- categories, but no infrastructure for that exists yet.
-- Fix acceleration of second-declension adjectives: feminine is missing.
