• Describe the difference between regular and irregular verbs.

VERBS
Verbs are words that show action or existence. Every sentence must have at least one verb. Verbs indicate action by the subject. They may also express existence or description of the subject.
Examples: Bob ate my lunch. (The subject Bob performs the action of the verb ate.)
This lesson is extremely easy. (The subject lesson exists as shown by the verb is.)
The English language has six verb forms: base, infinitive, present, past, present participle, and past participle. Some take endings while the infinitive adds the word to. They are listed in the table below with the changes in bold.
