What counts as a hiatus?

A hiatus occurs when one vowel is immediately followed by another vowel and they do not form a diphthong.

Regular diphthongs

αι, ει, οι, αυ, ευ, ου, ηυ, ωυ

Diphthongs with iota subscript / adscript

At least one hiatus type must be selected.

Optional Hiatus Rules Break hiatus when a dash intervenes Break hiatus across select punctuation (.,;:·) Break hiatus if second sound has rough breathing Only detect same-sound hiatus (e.g. α–α, αι–αι; accent-insensitive, diphthong-aware; experimental)

These options are disabled by default.
