This study examines the occurrence of increments in three languages (Nigerian English, Yoruba, and Pidgin) in the medical context in Nigeria with the aim to give a functional classification to increments built upon the conceptual and structural description in the literature. This is a step further from reflecting the manifestation of increments in the monotypic context of mundane interactions to an investigation of the phenomenon in an institutional context. Fifty audio-taped recordings of naturally occurring conversations in selected hospitals in three states in southwest Nigeria were transcribed and analysed using Conversation Analysis. Functional classification of increments in the data revealed six types of increments namely, symptom-motivated, information-motivated, history-related, face-saving, emphatic, and mundane. The increments were mainly glue-ons and very few instances of non-add-ons in the context of history-related increments. Patients were more frequently disposed to designing increments than doctors in STI and HIV consultations in Nigeria. The patients utilized the symptom-motivated increments for the purpose of elaborating on their health concerns and for clarifying the most pressing symptoms. This afforded them the opportunity of unburdening their health concerns and focalising more pressing symptoms. In addition, the sensitive nature of their condition also spurred the deployment of face-saving and history-related increments to handle embarrassing and face-sensitive questions about their condition and lifestyle.
