What do you call an English Verb base form?

The base form of an English verb is typically called the infinitive.

Here's why:

* Infinitive: This is the basic, unconjugated form of a verb, usually preceded by "to." For example: "to walk," "to eat," "to sing."

* Base form: This term is more general and refers to the verb without any inflectional endings (like "-s," "-ed," or "-ing"). It's the starting point for creating other verb forms.

While both terms are correct, "infinitive" is the more specific and commonly used term for the base form of a verb.
