The simple present tense is one of the most common tenses in English.
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":
|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.
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|
|consonant + y||Change Y to I, then add -ES||It flies|
|[anything else]||Add -S||He sings|
