the inversion of ri: {| | || ᕆ || || || || ri || |- | ᕋ || || ᕈ || || ra || || ru |- | || ᕂ || || || || rai || |} The remaining sounds are written with digraphs. A raised ra is prefixed to the k-series to create a digraph for q: qa, etc.; the final is -q. A raised na-ga is prefixed to the g-series to create an ng () series: nga, etc., and the na is doubled for geminate nng (): nnga. The finals are and . In Nunavut, the h final has been replaced with Roman , which does not rotate, but in Nunavik a new series is derived by adding a stroke to the k-series: ha, etc. In the early years, Roman Catholic and Anglican missionaries used slightly different forms of syllabics for Inuktitut. In modern times, however, these differences have disappeared. Dialectical variation across the syllabics-using part of the Inuit world has promoted an implicit diversity in spelling, but for the most part this has not had any impact on syllabics itself. Derived scripts At least two scripts derive from Cree syllabics, and share its principles, but have fundamentally different letter shapes or sound values. Blackfoot Blackfoot, another Algonquian language, uses a syllabary developed in the 1880s that is quite different from the Cree and Inuktitut versions. Although borrowing from Cree the ideas of rotated and mirrored glyphs with final variants, most of the letter forms derive from the Latin script, with only some resembling Cree letters. Blackfoot has eight initial consonants, only two of which are identical in form to their Cree equivalents, se and ye (here only the vowels have changed). The other consonants were created by modifying letters of the Latin script to make the e series, or in three cases by taking Cree letters but reassigning them with new sound values according to which Latin letters they resembled. These are pe (from ), te (from ), ke (from ), me (from ), ne (from ), we (from ). There are also a number of distinct final forms. The four vowel positions are used for the three vowels and one of the diphthongs of Blackfoot. The script is largely obsolete. Carrier and other Athabaskan Athabaskan syllabic scripts were developed in the late 19th century by French Roman Catholic missionaries, who adapted this originally Protestant writing system
