The role of intonation in Eskimo Pidgin is not mentioned in the sources, but it is likely that it is involved in the expression of interrogative. Apart from intonation, the data suggest that there is no other marking. Stefánsson (1909: 222) writes: "Any jargon word may by itself be used as a question, or any other combination of words may be so used." His final remark that "The question, if not required by the context, is indicated by inflexion" is not corroborated by the data.
