Answer :
The answer is an overextension error. This is a mistake in early word use in which a kid utilizes a solitary word to mark numerous diverse things in a way that is conflicting with grown-up utilization. There are three kinds of overextensions. Downright overinclusions include utilizing single word inside a classification to name a firmly related referent that falls in a similar classification. Cases are found in references to individuals (e.g. daddy for all men), creatures (e.g. canine for stallions and different quadrupeds), vehicles (e.g. truck for transport), sustenances (e.g. apple for oranges), and various different classifications.
