What is core vocabulary?
Core vocabulary is a small set of simple words, in any language, that are used frequently and across contexts (Cross, Baker, Klotz & Badman, 1997). Core vocabulary contains all parts of speech – nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections and serves as a great medium for teaching language.
From toddlers to seniors, core’s simple words make up 80 percent or more of everyday communication and are the heart of language development. Action words like “want,” “put,” “get,” nouns like “thing,” “stuff,” and “people,” pronouns like “I, me, my, mine,” and “he, she, it, them,” form easy sentences with demonstratives like “this” and “that.” Early adverbs like “here” and “there” enable all students to express themselves. “Put it here,” “Get me this,” and “I want that” are what young children say when they are building sentences (Minspeak).
Teaching core vocabulary is fundamental to teaching AAC. Here are some introductory resources on core:
