4 Principal Parts of Verbs
Every verb has four basic forms called its principal parts: the present: describes an unchanging, repeated, or recurring action that exists only now. It can also represent a widespread truth. I sail the Seven Seas. Democracy is our form of government. the present participle: describes an action that is ongoing. I am sailing the Seven Seas. Senators are debating. the past: represents an action that started and has finished in the past. I sailed the Seven Seas. Our forefathers signed the Constitution. the past participle: references completed action. I have sailed the Seven Seas. These principal parts are used to make all of the forms and tenses (or conjugations) of the verb.
