The basic forms of Japanese verb are root form, nai form, ta form and nakatta form. We call these four forms "Plain Form".

The plain form can be used instead of masu form in casual situations.
Sentences that end with the plain form are less formal and each form refers to affirmative, negative and tense. In this usage, the plain form is also called the casual form.
