Simple tenses of a verb

Answer 1

When used in grammar 'simple' means one verb. The simple tenses only have one verb eg

I like ice cream = present simple

I ate the ice cream = past simple

In contrast other tenses have an auxiliary verb and a main verb or a be verb and a main verb or a modal verb and a main verb. eg have been, will see, is waiting, was eaten

Some people call present perfect, present perfect simple, but I think this is not correct. Most grammar books I have talk about 2 simple tenses - present and past.

Answer 2

The simple tenses of a verb are present simple, past simple, and future simple. They are used to indicate when an action takes place: present simple for actions happening now or regularly, past simple for actions that occurred in the past, and future simple for actions that will happen in the future.
