What term refers to how language is represented in the mind by creating meaningful sentences?

The term that refers to how language is represented in the mind by creating meaningful sentences is representation. This concept encompasses how individuals mentally construct, organize, and understand language as a systematic way of conveying thoughts and ideas. Representation in language involves both the structure of sentences (syntax) and the meaning conveyed (semantics).

The other terms listed do not specifically capture the broad and comprehensive nature of how language is represented. Lexical priming relates to how exposure to one word or phrase can influence the processing of related words, but it doesn't specifically address sentence construction. Syntactic coordination is focused on how sentences are formed in relation to one another, while semantic segmentation deals with breaking down language into meaningful units but does not necessarily describe the overall representation of sentences in the mind. Thus, representation effectively encapsulates the process of creating meaningful sentences in cognitive terms.
