Here is an example with the verb EAT.
|third person||he, she, it||eats||they||eat|
Note that the third person singular form has the morpheme -s added to the base form of the verb. All the other persons are the same. There are a few irregularities regarding the third person singular but they are very simple to understand and the same rules that apply to making singular nouns plural. Here are the rules:
For verbs that end in -ch, -o, -s, -sh, and -x, add -es to create the third person singular.
|3rd per||he, she, it||teaches||they||teach|
|3rd per||he, she, it||goes||they||go|
|3rd per||he, she, it||focuses||they||focus|
|3rd per||he, she, it||washes||they||wash|
|3rd per||he, she, it||mixes||they||mix|
For verbs that end in a vowel + y, add -s.
|3rd per||he, she, it||says||they||say|
If the verb ends in a consonant + y, change y to i and add –es.
|3rd per||he, she, it||studies||they||study|
Note that a change only occurs with the third person singular. All other persons have the same conjugation.
The verb HAVE is irregular. Note that -ve is replaced with -s for the third person singular.
|3rd per||he, she, it||has||they||have|
The simple present in English may be used diffently than the simple present in your mother tongue. Learn how to use the simple present by going on to page 2 of this lesson.
Warning: there are two ways to pronounce the morpheme –es, and one of them adds another syllable to the verb. Learn about these two pronunciations by visiting the page on nouns.
