Specific to Spanish

Things that are only true of Spanish in NoaLingua

  • Spanish has the largest UniMorph dataset of any supported language: 1,196,245 rows, of which 1,048,576 are verb forms.
  • Unlike French and Italian, Spanish UniMorph also covers nouns (107,392) and adjectives (40,277), so declension lookups work rather than silently returning nothing.
  • Spanish is half of the default pair — a fresh install starts on English → Spanish.
  • The Spanish Wiktionary pack is 85 MB.
Setting up for Spanish Choose Spanish as the language you are learning in the extension popup or Settings → Languages. Packs begin downloading immediately and in the background — leave the browser open for 15 to 30 minutes and check the corner of the screen. When it goes quiet, everything is local.

Common questions about NoaLingua

Does NoaLingua work for Spanish?

Spanish is one of the 28 languages in the learning and translation selectors, and 5 of its ten capability axes are verified. The table on this page shows exactly which ones — including the ones that are documented as absent.

Can I get grammar tables for Spanish?

Yes. 50 MB · verbs (1,048,576), nouns (107,392) and adjectives (40,277) Conjugation and declension tables open at the exact form you clicked.

Does Spanish work offline?

Yes, once the packs finish downloading. Expect to leave the extension running 15 to 30 minutes after choosing your languages.

What does “not documented” mean in the table?

That we have not verified it ourselves, so we will not claim it either way. It is not the same as “no”. Several of those columns depend on data Chrome owns and does not publish per language.
