Unit 14: VERB FORMS
English verbs have very few forms. Most verbs are REGULAR and have four forms. It is easy to make these forms because they all change in the same way. But some important verbs are IRREGULAR, and we make their forms in different ways. Only the verb be (Unit 16) has more than five forms.
This is the form you can find in a dictionary.
