an overextension error

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.

For example Gabriel thinks that since her grandmother whom she calls 'Nona' has white hair then everyone with white hair can be called 'Nona' this is an overextension error.

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