Basic Sentence Structure

Every English sentence follows a fixed word order. Unlike many other languages, English does not allow you to rearrange words freely — the position of each word tells the reader who does what. The most common pattern is Subject + Verb + Object, often shortened to SVO.

Sarah reads books.

Sarah is the subject (who acts), reads is the verb (the action), and books is the object (what receives the action). Change the order, and the meaning breaks.

Subject + Verb

The simplest possible sentence has only two parts: a subject and a verb. No object is needed if the verb expresses a complete idea on its own.

The phone rang.
Sarah smiled.
The baby slept.
James arrived.

These verbs — ring, smile, sleep, arrive — describe actions that don't transfer to anything else. The subject does something, and the sentence is complete.

Subject + Verb + Object

Most English sentences add an object after the verb. The object answers the question what? or whom?

Daniel reads books.
She speaks English.
Anna called her brother.
Tom makes furniture.

The object always follows the verb. Moving it before the subject (Books reads Daniel) produces nonsense in English, even though it might be perfectly normal in other languages.

Subject + Verb + Complement

Some verbs do not describe an action — they describe a state. These are called linking verbs, and the most common one is be. Instead of an object, they take a complement: a word that describes or renames the subject.

Sarah is a teacher.
The coffee tastes good.
James seems tired.
That sounds interesting.

Common linking verbs include be, seem, become, look, feel, taste, sound, smell. The complement can be a noun (a teacher) or an adjective (good, tired).

Adding details: time and place

English sentences often end with extra information — when, where, or how something happens. This information comes after the object or complement.

She reads books every evening.
He works at Google.
Anna lives in Berlin.
Daniel plays football on Saturdays.

The typical order for extra details is place before time:

Maria studies at the library every morning.

Not every sentence follows this order rigidly, but it is the default and the safest choice at this level.

The subject always comes first

In English statements, the subject appears before the verb. This rule has almost no exceptions in everyday speech.

Many languages allow sentences without a visible subject. Spanish, for example, can say just Habla espanol — the ending of the verb tells you who speaks. English cannot do this. Even when the subject seems obvious, it must be stated.

She speaks English.

Dropping she and writing just Speaks English is not a complete sentence. English always requires an explicit subject.

The same applies to it and there when no real subject exists:

It is cold today.
It was midnight.

These sentences use it as a grammatical placeholder. Removing it (Is cold today) is a common mistake among learners whose native languages drop the subject.

Joining two ideas

A sentence can contain two complete ideas joined by a word like and, but, or or. Each half has its own subject and verb.

Sarah cooked dinner and Daniel washed the dishes.
He wanted to come, but he was busy.
We can meet on Monday or I can call you tomorrow.

A sentence can also have a main idea followed by a supporting clause that explains why, when, or under what condition.

I called Sarah because I needed help.
She left early because the meeting was cancelled.

Linking words like and, but, or, because, when, if are covered separately.

Common mistakes

Missing subject

Wrong word order: object before verb

Wrong word order: verb before subject

Missing "it" as placeholder

Extra details in the wrong position

Every morning she drinks coffee
She drinks coffee every morning
