The verb ‘study’ is classified as a regular verb. This means that it follows the standard pattern for forming its past tense and past participle. For regular verbs, you simply add ‘-ed’ to the base form to create the past forms.
For example, the base form is ‘study,’ and the past tense is ‘studied’ (pronounced /ˈstʌd.id/). Similarly, the past participle is also ‘studied.’ This consistent pattern is a key characteristic of regular verbs.
In contrast, irregular verbs do not follow this rule and often have unique forms for their past tense and participle. Examples of irregular verbs include ‘go’ (went) and ‘take’ (took). Since ‘study’ conforms to the regular pattern, you can confidently categorize it as a regular verb.
