The present simple is the first tense most learners meet, and the one English speakers use most. It sounds easy, but it hides two traps: the -s on he, she and it, and the way questions and negatives need do or does. Get those two right and the rest follows.

How to form the present simple

For I, you, we and they, the verb is just the base form. For he, she and it, you add an ending.

The third-person spelling rules

The ending is almost always -s, but a few verbs take -es or change their spelling:

Two common verbs are irregular here: have becomes has, and be becomes am (I), is (he/she/it) and are (you/we/they).

Questions and negatives: do and does

This is where most of the trouble lives. The present simple does not form questions or negatives on its own. It borrows the auxiliary verb do (for I, you, we, they) and does (for he, she, it).

• Negative: don't / doesn't + base form. I don't smoke. She doesn't eat meat.
• Question: do / does + subject + base form. Do you live here? Does he speak French?

The key rule: once you use does, the main verb drops its -s. The ending is only added once. So it is Does she like coffee? and not Does she likes coffee? Likewise He doesn't want it, never He doesn't wants it.

The verb be is the exception. It needs no auxiliary: Are you ready? She isn't here.

When to use the present simple

There are four main jobs.

1. Permanent facts and general truths

Things that are always or generally true.

• Water boils at 100 degrees.
• The sun rises in the east.
• Bees make honey.

2. Habits and routines

Things you do regularly. These often appear with frequency adverbs or time phrases like every day or on Mondays.

• I get up at seven.
• She drinks tea every morning.
• We visit my parents on Sundays.

These are not happening at the moment of speaking; they are patterns that repeat. That is the heart of the present simple: it describes the rule, not the single event in front of you.

3. Timetables and schedules

Fixed future events set by a timetable, even though they are still to come.

• The train leaves at nine.
• The film starts at eight.
• The shop opens tomorrow.

4. Instructions and commentary

Steps in a process, directions, demonstrations and live sports commentary.

• You take the second left, then you cross the bridge.
• First you heat the oil, then you add the onions.
• Messi passes to Suarez, who shoots and scores.

The confusion this page resolves: a present tense for the future

The timetable use surprises a lot of learners. The train leaves at nine describes an event that has not happened yet, so why is it a present tense? Because timetables and schedules belong to a fixed system that is true now. The departure is already set, printed and unchangeable, so English treats it as a present fact rather than a personal plan.

The test is whether a timetable, calendar or programme decides the time:

• The match starts at three. (the fixture decides)
• Term ends on Friday. (the calendar decides)
• My flight departs at noon. (the schedule decides)

Compare that with a personal arrangement, where English uses other forms: I am meeting Sam at three (present continuous) or I am going to call her later. The present simple is reserved for the timetable, not the plan you made yourself.

Adverbs of frequency

Words like always, usually, often, sometimes, rarely and never tell you how often something happens. Their position is fixed and catches learners out.

The rule: before the main verb, but after the verb be.

So I always am late is wrong; it has to be I am always late. With do/does the adverb still sits before the main verb: He doesn't usually work weekends.

Stative verbs prefer the present simple

Some verbs describe states rather than actions: thoughts, feelings, senses and possession. These verbs are normally used in the present simple, not the continuous, even when you mean "right now".

Common stative verbs: like, love, hate, want, need, know, believe, understand, remember, mean, belong, own.

• I want a coffee. (not I am wanting)
• She knows the answer. (not She is knowing)
• Do you believe him? (not Are you believing)

Present simple vs present continuous

This is the split that confuses most learners. The short version:

If the action is general, repeated or permanent, use the present simple. If it is in progress right now or temporary, use the present continuous. A quick check: ask whether you could add every day or right now. I work here every day takes the simple; I am working right now takes the continuous. For the full picture, see the present continuous guide.

Common mistakes

Ranked by how often they actually appear.

1. Dropping the third-person -s. He go to work by bus should be He goes to work by bus. This is the single most common present simple error, and it marks you as a beginner more than almost anything else.
2. Adding -s after does or doesn't. Does she likes it? He doesn't wants it. The auxiliary already carries the ending, so the main verb is bare: Does she like it? He doesn't want it.
3. Using be with a present simple verb. I am agree, I am think, I am want. These verbs need no be: I agree, I think, I want. English uses be only with adjectives and the continuous, not with an ordinary present simple verb.
4. Forming questions without do/does. You like pizza? She lives here? In writing and careful speech you need the auxiliary: Do you like pizza? Does she live here?
5. Wrong frequency-adverb position. I always am tired and She drinks always coffee are both wrong. It is I am always tired and She always drinks coffee.

Practice

Choose the correct form. Answers are below.

1. She ___ (watch) television every evening.
2. ___ he ___ (speak) English?
3. They ___ (not / live) in this city.
4. The train ___ (leave) at half past six.

Answers: 1. watches (third person, verb in -ch takes -es) 2. Does ... speak (does + base form, no -s on speak) 3. don't live 4. leaves (a timetable, so present simple even though it is in the future) 5. am always (frequency adverb after be)
