Bukk /bʊk/ is a family of languages, also known as bukkean languages, which were spoken in what was northern Tarnaria and in Overpol Expanse, later Overpol Region. They are using the bukkean tone modifiers of the Root Tongue.

Bukk influences are seen in many names which would pronounce 'o' as 'u', in names such as Done, Ton and Dod. It is also customary to see the letter “u” pronounced as “oo”, just like the name of the language itself, bukk, is pronounced as the word “book”.

Bukkean languages have a characteristic intonation of finishing a phrase or a sentence with the tone going up, which to a foreigner might sound like the speaker is counting or listing items off. This monotonous quality is widely regarded as aesthetically pleasing and also a sign of nobility when utilized in formal situations, such as weddings, funerals and legal proceedings. Mandae is frequently read with a similar monotonous intonation, albeit with a different tonal pattern.
