CHAPTER 2. THE SIMPLE PRESENT OF VERBS OTHER THAN THE VERB TO BE

1. Formation of the simple present
The Simple Present of any verb other than the verb to be is formed from the bare infinitive of the verb. As shown in the following examples, the bare infinitive of a verb consists of the infinitive without the word to. The bare infinitive is the form in which English verbs are usually listed in dictionaries. For example:

Infinitive	Bare Infinitive
to be	be
to walk	walk
to work	work

In the Simple Present of verbs other than the verb to be, the form of the verb used with the subjects I , you, we and they is the same as the bare infinitive. The form of the verb used with the subjects he, she and it has the ending s added to the bare infinitive.

For example, the Simple Present of the verb to work is conjugated as follows:

I work

you work

he works

she works

it works

we work

they work

The form of the verb used with the subjects he, she and it is generally referred to as the third person singular

See Exercise 1.

a. The simple present of the verb To Have
The Simple Present of the verb to have is slightly irregular, since the bare infinitive is have, whereas the form of the verb used in the third person singular is has. The Simple Present of the verb to have is conjugated as follows:

I have

you have

he has

she has

it has

we have

they have

See Exercise 2.

2. Spelling rules for adding s in the third person singular
Some verbs change their spelling when s is added in the third person singular.

a. Verbs ending in y
The English letters a, e, i, o and u are generally referred to as vowels. The other English letters are generally referred to as consonants.

When a verb ends in y immediately preceded by a consonant, the y is changed to ie before the ending s is added. In each of the following examples, the consonant immediately preceding the final y is underlined.

Bare Infinitive	Third Person Singular
study	studies
fly	flies
carry	carries

However, when a verb ends in y immediately preceded by a vowel, the y is not changed before the ending s is added. In each of the following examples, the vowel immediately preceding the final y is underlined.

Bare Infinitive	Third Person Singular
say	says
enjoy	enjoys
buy	buys

See Exercise 3.

b. Verbs ending in o
When a verb ends in o, the letter e is added before the s ending. For example:

Bare Infinitive	Third Person Singular
do	does
echo	echoes
go	goes

c. Verbs ending in ch, s, sh, x or z
When a verb ends in a sibilant sound such as ch, s, sh, x or z, the letter e is added before the s ending. For example:

Bare Infinitive	Third Person Singular
pass	passes
push	pushes
watch	watches
fix	fixes
buzz	buzzes

See Exercise 4.
3. Pronunciation of the es ending
A syllable is a unit of pronunciation, usually consisting of a vowel sound which may or may not be accompanied by consonants.

When a verb ends in a sibilant sound such as ch, s, sh, x or z, the es ending of the third person singular is pronounced as a separate syllable. The reason for this is that these sounds are so similar to the sound of the es ending, that the ending must be pronounced as a separate syllable in order to be heard clearly.

In each of the following examples the bare infinitive consists of one syllable, whereas the form of the verb used in the third person singular consists of two syllables.

Bare Infinitive	Third Person Singular
pass	passes
push	pushes
catch	catches
mix	mixes

Similarly, when s is added to verbs ending in ce, ge, se or ze, the final es is usually pronounced as a separate syllable. In each of the following examples the bare infinitive consists of one syllable, whereas the form of the verb used in the third person singular consists
of two syllables.

Bare Infinitive	Third Person Singular
race	races
rage	rages
praise	praises
doze	dozes

However, when s is added to a verb ending in e preceded by a letter
other than c, g, s or z, the final es is not pronounced as a separate syllable. In each of the following examples, both the bare infinitive and the form of the verb used in the third person singular consist of one syllable.

Bare Infinitive	Third Person Singular
make	makes
smile	smiles
dine	dines
save	saves

See Exercise 5.

4. The auxiliary Do
With the exception of the verb to be, verbs in modern English use the auxiliary do to form questions and negative statements in the Simple Present.
The Simple Present of the verb to do is conjugated as follows:

I do

you do

he does

she does

it does

we do

they do

Auxiliaries are verbs which are combined with other verbs to form various tenses. It should be noted that when an auxiliary is combined with another verb, it is the auxiliary which must agree with the subject, while the form of the other verb remains invariable.

When the auxiliary do is combined with another verb, the other verb always has the form of the bare infinitive.

a. Questions
In order to form a question in the Simple Present of any verb other than the verb to be, the Simple Present of the auxiliary do is added before the subject, and the bare infinitive of the verb is placed after the subject. For example:

Affirmative Statement	Question
I work.	Do I work?
You work.	Do you work?
He works.	Does he work?
She works.	Does she work?
It works.	Does it work?
We work.	Do we work?
They work.	Do they work?

See Exercise 6.

b. Negative statements
In order to form a negative statement, the Simple Present of the auxiliary do followed by the word not is placed before the bare
infinitive of the verb. For example:

Affirmative Statement	Negative Statement
I work.	I do not work.
You work.	You do not work.
He works.	He does not work.
She works.	She does not work.
It works.	It does not work.
We work.	We do not work.
They work.	They do not work.

See Exercise 7.
In spoken English, the following contractions are often used:

Without contractions	With contractions
do not	don't
does not	doesn't

c. Negative questions
To form a negative question, the Simple Present of the auxiliary do is placed before the subject, and the word not followed by the bare infinitive is placed after the subject. However, when contractions are used, the contracted form of not follows immediately after the Simple Present of the auxiliary do. For example:

Without contractions	With contractions
Do I not work?	Don't I work?
Do you not work?	Don't you work?
Does he not work?	Doesn't he work?
Does she not work?	Doesn't she work?
Does it not work?	Doesn't it work?
Do we not work?	Don't we work?
Do they not work?	Don't they work?

See Exercise 8.

d. Tag questions
The auxiliary do or does is used for a tag question which follows a statement containing the Simple Present of a verb other than the verb to be. In the following examples, the negative tag questions are underlined. Contractions are usually used in negative tag questions.

Affirmative Statement	Affirmative Statement with Tag Question
I work.	I work, don't I?
You work.	You work, don't you?
He works.	He works, doesn't he?
She works.	She works, doesn't she?
It works.	It works, doesn't it?
We work.	We work, don't we?
They work.	They work, don't they?

See Exercise 9.

e. The verb To Have
It should be noted that, particularly in British English, in the case of the Simple Present and Simple Past of the verb to have, questions and negative statements are sometimes formed in the same way as for the verb to be, without the use of the auxiliary do.
e.g. He has a sister, hasn't he?
