You have words. Now, let's put them together to make ideas. In English, the most common way to build a sentence is with a simple recipe: Subject-Verb-Object, or SVO.

Think of it like a mini-story. The subject is the hero, the verb is what the hero does, and the object is what's affected by that action. This structure is the foundation for almost all declarative sentences in English, which are statements that declare or state a fact.

We use the present simple tense to talk about habits, routines, and facts. These are actions that happen regularly or are generally true. It’s the tense for daily life.

• I drink tea in the morning.
• They live in New York.
• The Earth revolves around the Sun.

Some of the most common verbs are irregular, meaning they don't follow the usual patterns. Let's look at a few essential ones in their present simple form: to be, to have, and to go.

The verb to be is special. It doesn't show action; it describes a state of being, an identity, or a quality. You use it to say who you are, what you are, or how you are.

• I am a teacher.
• You are happy.
• He is my brother.

Action verbs, on the other hand, describe what the subject does. Compare these:

• She is a writer. (Her identity)
• She writes books. (An action she performs)

In the present simple, there's one key rule to remember. When the subject is third-person singular—he, she, or it (or a name like Maria or the dog)—the verb usually gets an -s or -es at the end. This is a fundamental part of verb conjugation in English.

If the verb ends in -o, -ch, -sh, -ss, -x, or -z, you add -es. For most others, you just add -s.

This rule applies to action verbs. The irregular verbs to be and to have follow their own special patterns:

• I am, you are, he/she/it is
• I have, you have, he/she/it has

To make sentences more descriptive, you can add adverbs of frequency. These words tell us how often an action happens. Common ones include always, usually, often, sometimes, rarely, and never.

The most common placement for these adverbs is right before the main verb.

• I always drink coffee in the morning.
• He usually walks to work.

However, there's an exception. When you use the verb to be, the adverb comes after it.

Notice the difference? For action verbs, the adverb comes before. For to be, it comes after. Mastering this small rule will make your sentences sound much more natural.

Great work. You now have the fundamental tools to build clear, declarative sentences in English. Practice by describing your own daily routines and the people around you.
