If vegetables could talk …: A structural and sequential analysis of buying and selling interactions in a Mexican fruit and vegetable shop

Abstract

The present investigation studies buying and selling encounters in a Mexican fruit and vegetable shop. It is a conversation-analytic study that shows aspects of the institutional character of these interactions, their overall organisation and sequential structure. It suggests that the core sequential structure of these encounters consists of two base adjacency pairs, buying (requesting–giving a product) and selling (requesting–giving money). In particular, the analysis describes the preparatory characteristics of the pre-expansions that precede the product request formulations, the linguistic composition and sequential positioning of request formulations, the insertions of the buying adjacency pair and the sequencing of the commercial exchange which is described as the climax of the institutional event. The designs of the first pair part of the selling adjacency pair and the product request formulations are presented as clear instances of the referential framework or common ground shared by seller and customer.
