Present Simple
Learn how the present simple is formed, what it is used to describe, and how frequency adverbs and spelling rules fit into the picture.
The everyday tense
The present simple describes what is regular, permanent or true.
The present simple describes habits, general truths, permanent situations and scheduled events. It uses the base form of the verb, with -s added when the subject is he, she or it.
In She works at a hospital., Water boils at 100 degrees. and The train leaves at nine., each sentence describes something regular, permanent, or fixed by a schedule, rather than something happening at this exact moment.
This lesson covers how the present simple is formed, its main uses, and the details that often trip learners up.
The central idea
The present simple describes a pattern, not a moment.
Compare a present simple sentence with a present continuous sentence describing the same subject.
01
Present simple
She works at a hospital.
02
Present continuous
She is working right now.
The useful question is: is this a pattern, or a snapshot of this exact moment?
The first sentence describes her job, a regular pattern true regardless of the moment it is said. The second describes what she is doing right now, at this specific moment.
Forming the present simple
Most subjects use the base form; one group adds -s.
I, you, we and they use the base form
I work. They work.
He, she and it add -s
He works.
Spelling rules for the third person -s
A few endings call for a small adjustment.
Most verbs → add -s: work → works
Verbs ending -s, -ss, -sh, -ch, -x or -o → add -es: watch → watches, go → goes
Verbs ending in a consonant plus y → change y to i, add -es: study → studies
Have → irregular: have → has
Negatives and questions
Do or does carries the negation or the question.
Negative: do not / does not
She doesn’t work on Sundays.
Question: do or does before the subject
Does she work on Sundays?
The main verb returns to its base form once do or does is present. This pattern is covered in more depth in the Negatives and Question Formation sections.
What the present simple describes
Four situations call for this tense.
Habits and routines
She walks to work every morning.
General truths and facts
The sun rises in the east.
Permanent situations
He lives in Toronto.
Scheduled events
The train leaves at nine.
Even a future event can use the present simple when it follows a fixed timetable.
Frequency adverbs
These words often accompany the present simple.
always → She always arrives early.
usually → He usually skips breakfast.
often → They often work late.
sometimes → It sometimes rains in April.
rarely → She rarely complains.
never → He never arrives on time.
Position
A frequency adverb is usually placed before the main verb, but after a form of be.
A useful decision guide
Ask whether this describes a pattern, and check the subject.
01
Does this describe a habit, fact, permanent situation, or schedule?
If so, the present simple usually fits.
02
Is the subject he, she or it?
If so, add -s, -es, or use “has” for the verb “have”.
03
Is this a negative or a question?
Use do or does, and return the main verb to its base form.
04
Is a frequency adverb present?
Place it before the main verb, or after a form of be.
Common mistakes
The -s ending and the choice of tense are the most frequent slips.
The -s is not left off a third person singular subject.
Not: She work at a hospital.
Correct: She works at a hospital.
A verb ending in a consonant plus y changes to i before -es.
Not: She studys every evening.
Correct: She studies every evening.
The present simple is not used for something happening right now.
Not: Look, she works in the garden right now.
Correct: Look, she is working in the garden right now.
An action happening at this exact moment usually calls for the present continuous instead.
Check your understanding
Which form correctly completes each sentence?
Choose the correct answer for each sentence.
He __________ the news every evening.
✅ Exactly! Verbs ending in -ch add -es.
❎ Not quite. Does “watch” end in -ch?
Compare this to “watch” becoming “watches” like “go” becomes “goes”.
Which sentence is a general truth, best expressed with the present simple?
✅ Exactly! A permanent, general fact calls for the present simple.
❎ Not quite. Is this describing a fact, or something happening at this exact moment?
Does this fact ever change?
Which sentence places the frequency adverb correctly?
✅ Exactly! The frequency adverb comes before the main verb.
❎ Not quite. Check where “always” sits relative to “arrives”.
Does the frequency adverb come before or after the main verb?
Choose the best explanation
Select the sentence that explains the mistake correctly.
Why is “She work at a hospital.” not correctly formed?
✅ Exactly! Third person singular subjects need the -s ending in this tense.
❎ Not quite. Look at the subject and the ending on “work”.
Why is “Look, she works in the garden right now.” unnatural?
✅ Exactly! “Right now” points to this exact moment, which calls for the present continuous.
❎ Not quite. Focus on what “right now” signals about when this is happening.
Quick review
