Tom Scovel writes, “Overgeneralization means that whenever learners encounter a new rule or pattern in the target language, they assume the rule or pattern operates without exception” (53). In other words, overgeneralization describes the act of applying a linguistic/interlinguistic rule in situations when an exception rather than the rule is called for. Children and language learners alike overgeneralize as a natural part of the language acquisition process as they deploy what they already know about a language and in the process discover its limitations through feedback or negotiation.
Here are some examples of overgeneralization:
“I hurted myself.” (overgeneralization of the past tense -ed rule)
“My friend told me he saw sheeps on his way to school.” (overgeneralization of the plural + -s rule)
“Why you do go to that party?” (overgeneralization of S-V-O word order)
