This document discusses regular verbs in English. It explains that regular verbs follow predictable patterns in forming their tenses. For the present tense, most regular verbs just add -s in 3rd person singular. For the past tense, regular verbs typically add -ed. For the past participle, the same rules for forming the past tense apply. Some exceptions are noted for verbs ending in consonant+y or vowel+y. The key distinction is that regular verbs form their past tense and past participle in a predictable way by adding -d or -ed, while irregular verbs have irregular past forms.
