Question

Difference between simple present and present indefinite examples

Answer 1

What is the difference between simple present tense and present indefinite tense?

Two different names for the same thing really. As a name, present simple can be a little confusing because we actually don’t use this tense to talk about what we’re doing right at this moment. Present indefinite describes the way this tense works more accurately. We use it to talk about actions we perform regularly:

I go to work every day.

He drives into the city once a week.

We travel to North America every Christmas.

You can see from these examples that this tense doesn’t actually refer to the present moment. If you want to talk about what you or someone else is doing right now, you need to use the present continuous tense and use the verb ‘to be’ + verb + -ing:

I am writing a letter right now. (I’m writing a letter right now.)

They are driving to New York at this moment. (They are driving to New York at this moment.)
