A regular verb is one that conforms to the usual rule for forming its simple past tense.
In English, the "usual" rule is to add -ed or -d to the base form of the verb to create the past forms.
Examples:
Add "ed" to most verbs:
- jump > jumped
- paint > painted
If a verb of one syllable ends [consonant-vowel-consonant], double the final consonant and add "ed":
- chat > chatted
- stop > stopped
If the final consonant is w, x or y, don't double it:
- sew > sewed
- play > played
- fix > fixed
If the last syllable of a longer verb is stressed and ends [consonant-vowel-consonant], double the last consonant and add "ed":
- incur > incurred
- prefer > preferred
If the first syllable of a longer verb is stressed and the verb ends [consonant-vowel-consonant], just add "ed":
- open > opened
- enter > entered
- swallow > swallowed
If the verb ends "e", just add "d":
- thrive > thrived
- guzzle > guzzled
If the verb ends [consonant + "y"], change the "y" to an "i" and add "ed":
- cry > cried
- fry > fried
