* English: This is the dominant language and is spoken by almost everyone.
* Shetlandic: This is a dialect of Scots, which is a language in its own right, but is often considered a dialect of English. It is spoken by a large proportion of the population, especially in rural areas. Shetlandic has its own unique vocabulary, grammar, and pronunciation.
* Norn: This is an extinct language that was once spoken in Shetland, closely related to Old Norse. While it's no longer spoken as a living language, there are traces of Norn vocabulary and grammar that remain in Shetlandic and some place names.
Therefore, while English is the primary language, there is a strong local dialect of Scots, known as Shetlandic, which is widely spoken.
