THE SIMPLE PRESENT

The simple present tense is one of the most common tenses in English. This page will explain the rules for forming the tense with regular verbs.

1. Forming the simple present tense

There are only two basic forms for the simple present tense; one ends with -s and the other doesn't. Here are the rules, using the example verb "sing":

Subject	Verb Form	Example
I	simple form	I sing
You	simple form	You sing
He	simple form + S	He sings
She	simple form + S	She sings
It	simple form + S	It sings
We	simple form	We sing
They	simple form	They sing

2. -s or -es ?

With most verbs, the third person singular form is created simply by adding -S. However, with some verbs, you need to add -ES or change the ending a little. Here are the rules:

Verb ending in...	How to make the 3rd person singular	Example
s	Add -ES	He passes
z	Add -ES	She waltzes
sh	Add -ES	She wishes
ch	Add -ES	He watches
x	Add -ES	She mixes
o	Add -ES	He goes
consonant + y	Change Y to I, then add -ES	It flies
[anything else]	Add -S	He sings
