This study set out to check the addressing behavior within men’s and women’s talk in the written conversations in English language textbook series titled ‘New Interchange book’ by Richards, Hull and Proctor, (1998) from Cambridge University Press. In line with this aim, the present researchers initially prepared descriptive tables for both formal and informal contexts in three theme categories (Social, Cultural & Economic) vis a vis four case appropriations (men*men, men*women, women*men, women*women). The distributions of interlocutors were coded through content analysis techniques. The major findings indicated that the highest percentage of detected address terms belonged to pronouns (67.7%). The proportions for gender appropriations between interlocutors for this address term showed that the case condition with women to men (52.3%) and men to women (36.4%) had the highest rates as compared with other cases. Then, in the final stage, the datasets were scrutinized in terms of theories on gender disparity in the instructional materials. This paper has some pedagogical implications in terms of addressing term inequality as mapped on gender status within ELT books, which might indirectly change the balance against full and rich contexts for effective learning to occur.
