I recently skimmed a grammar of Faroese [0]. Not much has been written about the language in English; only a few books, and an English-Faroese dictionary was only first published in the 1980s.

It's spoken by about 50,000 people in the Faroe Islands, which are between Iceland and Scotland. The isles were settled by Viking-era Norse about a thousand years ago and then largely forgotten by the rest of the world. But they kept speaking their version of Old Norse and it became its own language. There are many dialects and the writing system was designed to cover all of them, so it is is etymologically informed by Old Norse and it is very conservative. It's not at all indicative of how it's really pronounced. The written form is somewhat even mutually intelligible with Icelandic / Old Norse, but the spoken language is not.

Underneath those æ and ð is a language that is oddly similar to English, like parallel convergent evolution. It's a North Germanic language not a West Germanic language so the historical diversion point is about 1500 years ago.

But it has undergone an extensive vowel shift (but in a different pattern). And also like English, it has also undergone extensive affrication (turned into ch/j) of the stop consonants and reduction of final stops and intervocalic stops. It has the same kind of stress - vowel reduction interaction that English has. That further heightens the uncanny effect.

I came away with the impression that it is English's closest sibling language, aside from Dutch. Some vocabulary:

broðir "broh-wer" (brother), heyggjur "hoy-cher" (hill/height), brúgv "brukf" (bridge), sjógvar/sjós "shekvar/shos" (sea), skyggj "skooch" (sky/cloud), djópur "cho-pur" (deep), veðirinn "ve-vir-uhn" (weather). Rough pronunciations given between quotes; all examples are cognate with English!

There's an extended story reading by a native speaker here [1] if you want an example of what it sounds like. No idea what they're saying. The intonation reminds me a bit of the northern British isles which also had a Norse influence.
