Although "youni" has not been regarded as a citation expression, it has a similar function and should be taught as one. We surveyed 35 academic papers to determine the number of times and the context in which "youni" was used. We found that "youni" was used in 40 places: 20 places where the source of information is followed by a summary, and 16 places where a direct quotation is followed by an interpretation of the quote. These two patterns are used differently. For first-year students it seems appropriate to start with the former, easier to understand pattern.
