Final answer:
Overgeneralization in language learning is when learners apply a rule to exceptions. For example, young children may say 'gooses' instead of 'geese' by overusing the rule for plurals.
Step-by-step explanation:
In language learning, overgeneralization refers to extending a language rule to an exception to the rule. For example, young children learning English may add an 's' to irregular plurals, saying 'gooses' instead of 'geese.' This shows their understanding of the general rule of adding 's' for plurals, but they have yet to learn the exceptions.
