This module generates the content of many Ancient Greek headword-line templates: {{grc-verb}}, {{grc-verb form}}, {{grc-noun}}, {{grc-noun form}}, {{grc-proper noun}}, {{grc-proper noun form}}, {{grc-adj-1&2}}, {{grc-adj-2nd}}, {{grc-adj-1&3}}, {{grc-adj-3rd}}, {{grc-adjective form}}, {{grc-part-1&2}}, {{grc-part-1&3}}, {{grc-adverb}}, {{grc-num}}, {{grc-preposition}}, {{grc-particle}}, {{grc-pronoun form}}.
This module tracks the monophthongs α, ι, υ (a, i, u) without macrons, breves, circumflexes, or iota subscripts (◌̄, ◌̆, ◌͂, ◌ͅ) with the tracking template grc-headword/ambig, so that length can be marked as policy requires, and it categorizes all Ancient Greek words into categories for accent type, such as Ancient Greek oxytone terms.
Experimentation on new features is done in Module:grc-headword/sandbox.
