The normative dictionary of Catalan — what the language academy says a word means and how it inflects. Monolingual, so it is a step up from a bilingual dictionary and worth making that step early: Catalan's closeness to Spanish and French makes a monolingual definition unusually easy to parse.

The Generalitat's language consultation service: a combined search across dictionaries, grammars and a large bank of resolved usage questions. When you are unsure whether a construction is correct Catalan or a Spanish calque — the commonest error for anyone who learned Spanish first — this is where the answer is.

Free multilingual dictionary with etymologies, IPA and full conjugation tables.

Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

Forvo

Multi-language

Crowd-sourced pronunciations of nearly any word by native speakers.
