The verb “to be”

Hamlet was right: to be or not to be—that is the question, of this post at least. What is the verb to be? How does it change in tense?
Forms of ‘to be’
The verb to be is deceptively simple, so try not to overthink it. To be describes existing: ‘I am’, ‘you are’, and ‘she is’ are all forms of ‘to be’. For a formal definition, Merriam-Webster Dictionary defines the verb ‘be’ as “to take place: to occur”. Anything that exists and experiences the state of being that the verb ‘to be’ describes.
Is ‘to be’ a regular or irregular verb?
Since being is taken literally as in existing, its use in English varies to refer to the past, present, or future. Verb tenses refer to the points in time at which things or people can be (read: exist). “To be” is a form of the base verb “am”. This makes it highly irregular in English since its other tenses (was, is, are, were) look nothing like “I am”.
Most English verbs undergo some change in form to show tense, and other information like count, subject, and so on. A verb’s tense is the point in time at which the action or event occurs. We can think of verb tenses as slices of time, and the three main tenses are past, present, and future.
Tense | Example |
---|---|
Past | My brother saw a movie yesterday. |
Present | I play football every weekend. |
Future | I will write that email tomorrow. |
Likewise, to be has various verb conjugations based on the number of subjects and the tense:
