Gaeilge · 1.7 million (some fluency) speakers · Lemmatizer: GiellaLT
Irish's grammatical mutations — séimhiú (lenition) and urú (eclipsis) — break naive word lookup, because the start of the word changes with grammar. Laesi ships a GiellaLT morphological analyzer that normalizes mutated forms back to the dictionary headword.
What the big apps miss
Mutations, normalized
bhfuil, gcaisleán, theach — eclipsed and lenited forms get mapped back to fuil, caisleán, teach so lookups actually work.
GiellaLT morphology
Irish is routed through GiellaLT's finite-state analyzer — the same academic-grade toolchain behind the Sámi languages.
For the Gaeltacht and the diaspora
Heritage learners, Gaeltacht residents, and the worldwide Irish-learning community get a reader that takes the language seriously.
