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 routes Irish through 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.
