“Goed” and “bringed” are examples of which concept in language?

The choice of "overgeneralisation" is correct because it refers to a common linguistic phenomenon where rules or patterns that apply to some cases are incorrectly applied more broadly than appropriate. In this instance, "goed" and "bringed" illustrate how a learner of English applies regular verb conjugation patterns to irregular verbs.

In English, most verbs form their past tense by adding -ed, so a child or language learner might overgeneralize this rule to irregular verbs like "go" and "bring." Instead of using the correct forms "went" and "brought," they apply the regular pattern, resulting in "goed" and "bringed." This reflects a developmental stage in language acquisition where learners are experimenting with language rules, showcasing their understanding while still making errors that reveal their learning process.

The other options do not accurately describe this phenomenon. Standard grammar pertains to established usage that is widely accepted in formal contexts, which these forms do not reflect. Neologism refers to newly coined words or expressions, while narrowing involves a word's meaning becoming more specific over time, which does not apply here.
