Spelling rules for the 3rd person singular

As a rule, the verb form of the 3rd person singular is added to s, however, there are a few rules for a series of verbal forms that are special:

1 .- When the verb already ends in s, or a similar sound as sh, ch or x:

watch -> watches dash -> dash

2 .- When the verb ends in or is also added:

go -> goes do -> does

3 .- When the verb ends in y, since it precedes a consonant, we have to change the y to i to add is below:

fly -> flies study -> studies

Note that these are the same spelling rules that apply to form the plural.

The Simple Present tense

Negative form

The structure of the negative structure is formed by adding the auxiliaries do or does plus the negation not

Do + not —> don’t
Does + not —> doesn’t

These auxiliaries are used TO HELP you. When you use the auxiliary the verb is always in its simple.

Remember:
In positive we had 2 conjugations for every verb (not to be)
- play/plays , work/works, study/studies, watch/watches, etc…

The conjugation is simple: HE / SHE / IT —- with the “s” form and I / WE / YOU / THEY —- simple form

Examples:
My brother works for IBM.
My parents live in Paris.

IN THE NEGATIVE FORM THE AUXILIARY CHANGES FORM AND NOT THE VERB.

He / she / it + doesn’t + verb (simple form)
I / We / You / They + don’t + verb (simple form)
