🇮🇸 The best dictionaries for learning Icelandic

Icelandic nouns have four cases in two numbers with definite and indefinite forms, and verbs are worse. BÍN gives you the complete table for any word instantly. It is the single most-used tool among Icelandic learners for a reason: you will look things up here several times a day for years.

A multilingual dictionary from Iceland's Árni Magnússon Institute, giving Danish, Swedish, Norwegian, Faroese, Finnish and English equivalents alongside recorded pronunciation. Better than a plain bilingual dictionary because seeing the Nordic parallels tells you which sense of a word is meant.

A single query box over the Árni Magnússon Institute's whole collection — dictionaries, inflection, etymology, usage rulings, terminology banks. Use it when you know a word exists but not which reference will explain it.

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.

Around 6 million words recorded by native speakers across 400+ languages, usually with several accents per word so you can hear regional variation. Free to search on the site; the paid tiers are aimed at API users and bulk audio downloads. Indispensable for names, place names and anything a TTS voice would mangle — many learners wire it directly into Anki for card audio.
