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

In other words, only THIRD PERSON SINGULAR subjects (he, she and it) have to have a verb with -S.

-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 dozes
sh	Add -ES	She wishes
ch	Add -ES	He watches
consonant + y	Change Y to I, then add -ES	It flies
[anything else]	Add -S	He sings
