1. Twelve (12) verbs, when used as auxiliary verbs, combine with the base form only (“base form” = infinitive minus “to”; for example: to go = infinitive; go = base form).
will would may do shall should might does can could must did
OK: I will go. You can go. He should go. We may go. They do go. Not OK: I will going. You can gone. He should goes. We may went. They do going.
2. Seven (7) verbs, when used as auxiliary verbs, combine with present participles (base form plus ing: for example, going ) OR past participles (I have walked. I have gone.)
am is are was were be been
OK: I am going. He is going. He is gone. You are going. You are gone. She was going. She was gone. We were going. We were gone. They will be going. They will be gone. It has been going. It has been gone. Not OK: I am go. I am went. He is goes. He was wenting. She will be goning.
Note: Been is the past participle of to be. But, none of the 7 verbs above combines with been. In fact, only three auxiliaries combine with been: have, has, had. One of these three is always immediately in front of been (for example: I have been sick. He has been sick. I had been sick.), except in the negative and interrogative (for example: I have not been sick. (negative) Has he been sick? (interrogative)). Also Note: Been cannot stand alone. For example: Not OK: I been here two years. OK: I have been here two years. Not OK: I been living here two years. OK: I have been living here two years.
