Answer:
The correct answer is overextension.
Explanation:
In the context of language acquisition, it refers to the erroneous over-generalization in the use of a word; that is, to the error that consists in extending the application of words to entities or objects not included in the concept or category of reference, even if they share certain characteristics. For example, the word "dog" is used to correctly designate dogs; but it is also used in reference to any other animal with "four legs."
