Errors in early word use or developmental errors are mistakes that children commonly commit when first learning language. Language acquisition is an impressive cognitive achievement attained by humans. In the first few years of life, children already demonstrate general knowledge and understanding of basic patterns in their language.
While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains an observable phenomenon in natural terms.
