Meanings

The Present Simple is the most basic tense in English. We use it to describe our daily routine, our habits, and general facts about the world. It tells people what 'usually' happens.

1

1. Daily Habits

Things you do again and again (every day, every morning, on Sundays).

“I drink coffee every morning.”

“He goes to the gym on Mondays.”

2

2. General Truths

Things that are always true or facts.

“The sun rises in the east.”

“Cats like milk.”

3

3. Permanent States

Things that don't change quickly.

“I live in London.”

“She works in a bank.”

Adverbs of Frequency

We use these special words to say HOW OFTEN we do something. For beginners, it is helpful to think of them as a scale from 100% (all the time) to 0% (none of the time).

Always 100%
(Every time)

We use "always" when we do something every time. There is no day or time when we don't do it.

I always brush my teeth in the morning.

Usually / Normally 90%
(Most days)

We use "usually" for things we do almost every day. It is our normal habit.

I usually walk to work, but sometimes I take the bus.

Often / Frequently 70%
(Many times)

We use "often" when we do something many times. It is common, but not every day.

We often watch movies on the weekend.

Sometimes 50%
(At times)

We use "sometimes" for things we do about half of the time. Not too much, not too little.

I sometimes drink tea instead of coffee.

Occasionally 30%
(Not very often)

We use "occasionally" for things we do once in a while. It doesn't happen very much.

We occasionally go to a fancy restaurant for dinner.

Seldom / Rarely 10%
(Almost never)

We use "rarely" when something almost never happens. It is very uncommon.

He rarely eats fast food because he likes healthy meals.

Hardly ever 5%
(Only once in a long time)

We use "hardly ever" when something happens only once in a long time. It is very close to "never".

I hardly ever see my cousins because they live far away.

Never 0%
(Not at any time)

We use "never" when something happens 0% of the time. We do not do it at any time.

I never smoke because it is bad for my health.

Where to put the adverb?

Subject + ADVERB + Main Verb

“He always arrives early.”

With the verb "To Be"

Subject + AM/IS/ARE + ADVERB

“They are usually very happy.”

In Questions

Do/Does + Subject + ADVERB + Verb?

“Do you often study at night?”

Present Simple: WH-Questions

Use these words to ask for information. The pattern is: WH-word + do/does + person + verb?

What (Things / Actions)

What do you eat for breakfast?

Where (Places)

Where does she live?

When (Time / Days)

When do you go to bed?

Who (People)

Who do they play with?

Why (Reasons)

Why does he cry?

How (Manner / Method)

How do you go to school?

Whose (Possession)

Whose book do you have?

Which (Choices)

Which color do you like?

⚠️

Important: The "Who" Rule

1. No "Do/Does" (Subject Question)

If "Who" is doing the action, just add -s to the verb.

"Who lives here?"

2. With "Do/Does" (Object Question)

If you ask about the other person, use do/does as normal.

"Who do you live with?"

Frequently Asked Questions

This is a historical leftover from Old English. It's the only person that kept a unique ending in the present tense.
Yes, but only for fixed schedules like The bus leaves at 9 PM or The concert starts tomorrow.
Use don't for I, You, We, They. Use doesn't only for He, She, It.
No. You should say I have a car. Never use am/is/are with another base verb.
Usually no. For things happening right now, we use the Present Continuous (I am eating).
These are verbs like know, love, and believe that describe states, not actions. They almost always use the Present Simple.
If there is a consonant before -y (like study), change it to -ies (studies). If there is a vowel (like play), just add -s (plays).
Use Does for He, She, It. Use Do for everyone else.
