The purpose of this essay is to study whether the linguistic behaviour of adult women using hedging and tags as indicative of an intrinsically tentative gender identity or of the effects of male dominant position through analyzing daily conversations of the heterosexual couples.The small scale study employs the methodology,namely,recording spontaneous and natural spoken conversation from authentic interaction with the permission of the ten male-female couples.Digital record pen with an omnidirectional microphone are placed in the central living area of each couple's home.Then discourse analysis provides data making it possible to support Fishman's claim that women use tag questions and 'you know' not because women are not being really sure of themselves,or are looking to the addressee for confirmation,but because men in a dominant position often refuse to take responsibility for the smooth conduct of interpersonal relations,women use tag questions and 'you know' to elicit and maintain conversations.
