The Present Simple has two main jobs in this area. The first is to describe habits — things you do regularly, repeatedly, as part of your routine. The second is to describe states — things that are simply true about you, your feelings, your mind, or your situation right now and in general.
Think of it this way: a habit is something you do again and again. A state is something you simply are or have — it exists without effort or action.
When something happens regularly — every day, every week, always, usually — you are describing a habit. The Present Simple is the tense for this. It does not matter whether you are doing the action right now. What matters is that you do it regularly.
A state is not an action — it is a condition. You cannot do a state; you simply have it or are in it. States are described with the Present Simple because they exist continuously — they are not happening right now in the same way a physical action happens. They are simply true.
Common state verbs include: know, believe, understand, think, feel, want, need, prefer, love, hate, like, own, have, belong, seem, appear, remember, forget, recognize, mean, contain, cost, weigh.
When the subject is he, she, or it (third person singular), you must add -s or -es to the verb. This is one of the most common mistakes in English.
-s → work → works, drink → drinks, know → knows-es → catch → catches, go → goes, teach → teaches-es → worry → worries, study → studies✗ She drink coffee every morning. · He go to the gym on Fridays.
✓ She drinks coffee every morning. · He goes to the gym on Fridays.
When the subject is he, she, or it, the verb must end in -s or -es. This is a grammatical signal in English that the subject is third person singular. Missing it makes the sentence sound unfinished.
✗ I am knowing the answer. · She is wanting a coffee. · He is owning a car.
✓ I know the answer. · She wants a coffee. · He owns a car.
State verbs describe conditions, not actions in progress. They do not have a "right now" dimension — they are simply true all the time. Because of this, you cannot use them in the continuous (-ing) form. Always use the Present Simple for states.
✗ She doesn't drinks coffee. · He don't work on Fridays.
✓ She doesn't drink coffee. · He doesn't work on Fridays.
In negative sentences, use do not / don't for I/you/we/they, and does not / doesn't for he/she/it. After doesn't, the main verb always returns to its base form — never add -s or -es. The auxiliary does carries the third-person information; the main verb does not need to change.
✗ I am going to the gym every Monday. · She is drinking tea every morning.
✓ I go to the gym every Monday. · She drinks tea every morning.
The Present Continuous describes something happening right now or around now temporarily. Habits are not temporary — they happen again and again as part of a fixed routine. Whenever you use a frequency adverb (every, always, usually, often), you almost certainly need the Present Simple, not the Continuous.
