Answer:an overextension error
Step-by-step explanation:
This is an error that occurs when a child at their young age use the same word for multiple unrelated things because they may be similarities in their mind which may mean that this is the same thing.

Gabriel has little ability to differentiate vocabulary at her age she then extends it use .
