The usual structure of a sentence is:
Subject + Verb + Object (SVO)
To make a sentence, you usually need:
-
a subject (S): the person, people or thing(s) doing the action
-
a verb (V): the action (can sometimes be separated into a main verb and an auxiliary verb)
-
an object (O): information that adds context to the subject’s action (when necessary)


This theatre company performs Hamlet.

I like Shakespeare’s comedies.

This play ended well.
Sometimes, adverbs or transition words can be added to the sentence.
Adverbs can be placed just before the verb.
S |
Adverb |
V |
O |
His characters |
often |
fight. |
|
We |
finally |
understood |
the character's pain. |
Adverbs can also be placed between the auxiliary verb and the main verb.

V |

When a transition word is placed at the beginning of a sentence, before the subject, use a comma after it.

To make a negative sentence in the simple present or simple past with to be, you usually need:
-
a subject: the person, people or thing(s)
-
the verb to be
-
the function word not
-
an object: information that adds context to the sentence

Subject |
to be + not |
Object |
Shakespeare |
was not |
an only child. |
You |
are not |
an actor. |
Cordelia |
is not |
greedy. |

“To be or not to be, that is the question."
Verbs other than to be use an auxiliary verb to form a negative sentence.
In this case, the structure usually is:
-
a subject: the person, people or thing(s) doing the action
-
the auxiliary verb: first part of the verb or helping verb.
-
the function word not
-
a verb: the action (in its base form)
-
an object*: information that adds context to the sentence (when necessary)

* The object is not always necessary.

Romeo will not court Juliet.

I do not like his comedies.

The audience was not listening quietly.
