How to form simple present tense

Out of all the different verb tenses, simple present tense is relatively, well, simple to form. The first general rule is to simply use the root of the verb, which is the form of a verb you will find if you look one up in our incredible dictionary, to form the first and second person constructions. For example: I walk. You dance. We run. They exist. Rivers flow.
The second general rule is that you add an -s or -es to the end of the root when used with nouns or pronouns in the third person singular. Typically, you would add an -es when a verb ends in -ch, -sh, –th, –ss, –x, or -z.

When you want to make affirmative sentences in the third-person singular, you need to add the third person 's' to the main verb. Here are some examples: The cat drinks water from this bowl. The main verb is 'drink' and the third person 's' is added to it since the subject is 'the cat.' She eats dinner at 9 P.M. The main verb here is 'eat,' and since the subject is 'she,' the verb changes to 'eats.'
