Inuktitut is written in several different ways, depending on the dialect and region, but also on historical and political factors.
Moravian missionaries, with the purpose of introducing the Inuit peoples to Christianity and the Bible, contributed to the development of an Inuktitut alphabet in Greenland during the 1760s that was based on the Latin script. (This alphabet is distinguished by its inclusion of the letter kra.) They later travelled to Labrador in the 1800s, bringing the Inuktitut alphabet with them.
The Alaskan Yupik and Inupiat (who, in addition, developed their own system of hieroglyphs) and the Siberian Yupik also adopted Latin alphabets.
Eastern Canadian Inuit were the last to adopt the written word when, in the 1860s, missionaries imported the written system Qaniujaaqpait they had developed in their efforts to convert the Cree to Christianity. The very last Inuit peoples introduced to missionaries and writing were the Netsilik Inuit in Kugaaruk and north Baffin Island. The Netsilik adopted Qaniujaaqpait by the 1920s.
The “Greenlandic” system has been substantially reformed in recent years, making Labrador writing unique to Nunatsiavummiutut at this time. Most Inuktitut in Nunavut and Nunavik is written using a scheme called Qaniujaaqpait or Inuktitut syllabics, based on Canadian Aboriginal syllabics. The western part of Nunavut and the Northwest Territories use a Latin alphabet usually called Inuinnaqtun or Qaliujaaqpait, reflecting the predispositions of the missionaries who reached this area in the late 19th century and early 20th.
In Siberia a Cyrillic script is used.
In April 2012, with the completion of the Old Testament, the first complete Bible in Inuktitut, translated by native speakers, was published.
