A study investigated the use of tag questions in the private conversations of Swedish men and women. Conversations took place in single-gender dyads (six with two men and six with two women) and six mixed-gender dyads. Informants were aged approximately 25 or approximately 50, of different social classes, chosen by random selection, and asked to engage in a conversation with a friend or relative. In this corpus, 350 of the 7,785 conversational turns, or 4.5%, ended with some kind of tag. The syntactic qualities, functions, and gender differences of the use of two tag questions, "va" ("OK? Right?) and "vet du" ("You know"), were examined. It is concluded that the two tag questions have different functions in conversation and are used in different conversational strategies, and that their usage can never be explained out of context. It is argued that a single variable such as tag question use can not be seen in isolation as an explanation of gender differences in language usage. The concept of conversational style is a more useful explanation. Women appeared to show more characteristics of a high-involvement style when in conversation with other women than when in conversation with their husbands. (MSE)
