Regular Verb
A regular verb follows the productive English inflection pattern, especially by forming its past simple and past participle with -ed or -d, with ordinary spelling adjustments such as “study” → “studied.”
Regular verbs form their past simple and past participle with the regular -ed/-d pattern, subject to normal spelling rules.
Key details
Important caveats
Scope Boundary
A verb is not regular merely because one form happens to look predictable; irregular verbs have lexically distinct past or participle forms that must be learned separately.
Further guidance
Application
Learn the base, -s, -ing, and -ed patterns together, including changes such as consonant + y → -ied and consonant doubling where applicable.
Core Rule
Regular verbs form the past simple and past participle with -ed (or -d when the base already ends in e), subject to normal spelling adjustments.
