Researchers in the field of linguistic have increasingly sought to link language development and the mind though cognitive theories of linguistics. This is in contrast to earlier explanations, which highlighted on language’s structure and linguistic pattern. In essence, these theories go beyond analyzing syntax, and look into association between language structure and cognitive standards that appear through human interaction. Cognitive theorists attached much importance to meaning in understanding language structure, and hence also influence semantic structures of languages. On the other hand, discourse theorists look into language patterns in every day language use (Gee, 2005).
