Inside the Fiercest Debate in Linguistics

A controversy among linguists which has been raging for a long time is the concept of universal grammar. Is there a fundamental set of rules that people use, no matter what their language is? There are certain features that almost all languages have in common, such as subjects, verbs, and objects, although their order can vary. But is this universal grammar due to something innate in the human brain, or did it come about when written language developed, or does it point to how languages were all originally related? Dr. Erica Brozovsky explains how linguists have disagreed, or even fought each other, over this controversy.
