What’s the Difference Between Is vs Was?

Is and was are both forms of the auxiliary verb “to be.” Is describes an event in the present tense, while was describes an event in the past tense.

Let’s look at each word in more detail along with their plural forms.

Is: Definition and Meaning

Is is the present continuous tense, third-person singular version of “to be.” It describes something that is happening now to one person or thing. For example, the sentence “she is running” describes a girl who is running now.

Alternatively, if you wanted to describe an event happening now to multiple people or things, use the word are. For example, “they are running” describes a group of people who are running now.

Was: Definition and Meaning

Was is the past continuous tense, third-person singular form of “to be.” It describes an action that happened in the past to one person or thing. For example, “he was cooking” describes a boy who used to be cooking, but now isn’t.

Alternatively, if you want to describe an event that has happened to multiple people or things, use the word were. For example, “they were cooking” describes a group of people who used to be cooking, but now aren’t.
