Fast mapping is a cognitive process that enables children to quickly acquire new vocabulary by inferring the meaning of a word from the context in which it is used. This ability allows them to make associations between unfamiliar words and concepts they already understand, facilitating rapid language development. Through exposure to new terms in context—such as through conversation, stories, or everyday experiences—children can guess the likely meaning of a word without needing extensive repetition or explicit definitions.

In the context of language acquisition, fast mapping plays a critical role in helping children expand their vocabulary and comprehension skills effectively. For example, when a child hears a new word during a story and can deduce its meaning from the overall narrative, they engage in fast mapping. This ability to guess the meaning from context not only enriches their language but also enhances their critical thinking and cognitive flexibility as they navigate and interpret their linguistic environment.
