Icelandic is spoken by about 400,000 people.
On our measured language map, its closest relatives are Faroese, Norwegian and Danish. If you speak one of those, much of the vocabulary will feel familiar from day one.
Structurally, verbs usually come before their objects.
Every lesson is built from 2,000 real Icelandic sentences, aligned with their translations word by word and piece by piece, so you always see how the sentence actually works instead of memorizing flashcards. The grammar is discovered from the sentences themselves, 1,678 patterns so far, and a spaced-repetition quiz teaches it in the order that unlocks the most of the language first. Our measured estimate for reaching conversational level from English is about 820 hours of study. Read how it works.
Most apps only teach Icelandic through English, if they teach it at all. These starting languages already have a built course, and any other published language can be paired on request:
Speaker figures follow Ethnologue and national censuses, rounded; the difficulty estimate is calibrated against U.S. Foreign Service Institute data.
