readily from one dialect to another, the presence of a particular vocabulary item in a given dialect is not a guarantee of the item's original source. Two groups of function words are characteristically Ottawa: the sets of demonstrative pronouns and interrogative adverbs are both distinctive relative to other dialects of Ojibwe. Although some of the vocabulary items in each set are found in other dialects, taken as a group each is uniquely Ottawa. Demonstrative pronouns Ottawa uses a set of demonstrative pronouns that contains terms unique to Ottawa, while other words in the set are shared with other Ojibwe dialects. Taken as a group the Ottawa set is distinctive. The following chart shows the demonstrative pronouns for: (a) Wikwemikong, an Ottawa community; (b) Curve Lake, an Eastern Ojibwe community; and (c) Cape Croker, an Ottawa community that uses a mixed pronoun set. The terms 'this (animate)', 'these (animate)', and 'these (inanimate)' are unique to Ottawa. Interrogative pronouns and adverbs Ottawa interrogative pronouns and adverbs frequently have the emphatic pronoun fused with them to form a single word. In this table the emphatic pronoun is written as -sh immediately following the main word. Other vocabulary A small number of vocabulary items are characteristically Ottawa. Although these items are robustly attested in Ottawa, they have also been reported in some other communities. Writing system Written representation of Ojibwe dialects, including Ottawa, was introduced by European explorers, missionaries and traders who were speakers of English and French. They wrote Ottawa words and sentences using their own languages' letters and orthographic conventions, adapting them to the unfamiliar new language. Indigenous writing in Ottawa was also based upon English or French, but only occurred sporadically through the 19th and 20th centuries. Modern focus on literacy and use of written forms of the language has increased in the context of second-language learning, where mastery of written language is viewed as a component of the language-learning process. Although there has never been a generally accepted standard written form of Ottawa, interest in standardization has increased with the publication of a widely used dictionary in 1985 and reference grammar in 2001, which provide models for spelling conventions. A conference held in 1996 brought together speakers of all dialects of Ojibwe to review existing writing systems and make proposals for standardization. Early orthographic practices 19th-century missionary authors who wrote in Ottawa include Catholic missionary Frederic Baraga and Anglican Frederick
