"Teacher-talk" is defined as speech used by teachers that is characteristically modified in four areas: phonology, lexis (consisting of morphology and vocabulary), syntax, and discourse. The phenomenon of teacher-talk has captured the attention of researchers for some time. Anyone who has ever taught English as a second or foreign language is aware of the immensity of the task. In fact, it is no longer deemed sufficient to teach the nuts and bolts of language-grammatical competence. Also important are sociolinguistic competence, the ability to produce and understand the appropriate remark at the appropriate time; discourse competence, the ability to produce a unified, coherent text in a given genre; and strategic competence, knowledge of how to repair, maintain, enhance, or facilitate communication.
