It shares features, including Schneider's Law, the reduction of alternate sequences of consonant clusters by simplification, with some Inuit dialects spoken in Quebec.

It is differentiated by the tendency to neutralize velars and uvulars, i.e. /ɡ/ ~ /r/, and /k/ ~ /q/ in word final and pre-consonantal positions, as well as by the assimilation of consonants in clusters, compared to other dialects.

Nor are the Labrador dialects uniform: there are separate variants traceable to a number of regions, e.g. Rigolet, Nain, Hebron, etc.

Nunatsiavut uses a Latin alphabet devised by German-speaking Moravian missionaries, which includes the letter ĸ (kra, often also written with an uppercase K).

In 1980, the Labrador Inuit Standardized Writing System was developed during a meeting with elders and educators to provide consistency and clarity.
