Irregular Verbs -- Important Notes Sample This: 01. Regular Verbs Regular verbs form their past tense and the past participle by adding “-ed” in the base (simple present) form. There are the following patterns for making regular Verbs: A: Base form (simple present) doesn’t end in “e”. We add “-ed” in base form to make the past tense and past participle. Example: abandon -- abandoned -- abandoned B: Base form (simple present) ends in “e”. We add “-d” in base form to make the past tense and past participle. Example: abase -- abased -- abased C: We repeat the last letter of the base form (simple present) in the past tense and past participle before adding “-ed”. Example: rag -- ragged -- ragged D: Base form (simple present) ends in “y” (and there is a consonant before “y”). We replace “y” with “i” in the past tense and past participle before adding “-ed”. Example: accompany -- accompanied -- accompanied 01A. Regular Verbs -- Pattern - 1 Base form (simple present) doesn’t end in “e”.
