Nativist theory:
Noam Chomsky introduced this theory. According to him our brain has an innate mechanism to generate lanugauge is called language acquisition device.
Child hears a sentences and words around them and it gives stimulation to the child's brain then the child starts to try to speak that.
A child not simply copying the sentences they hear around them.They will use the sentence which they heard whenever they need to use that.
Language development is a initiative and innate process of our brain.They not simply copying of the language of others not like modelism and behaviorism.If they copied they cannot produce a proper sentence in a meaningful way.Grammatic error is present in the initial phase. Then by the Child's own brain process it will be corrected unknowingly then the child begins to talk.
Initially child learns the words but them itself they know the difference for which is noun and verb and other phrases .This difference recognition is done by the innate mechanism.
It is the process for over 5 years, after that only the child matches the adult talk.
