The Definitive Guide to the Present Simple Tense
The Present Simple tense is the cornerstone of English grammar. Used far more often than people realize, mastering it is crucial for discussing routines, facts, and habits. This comprehensive guide breaks down the structure, rules, and common mistakes, ensuring you can use it fluently and correctly.
Construction: How to Form the Present Simple
The Present Simple is formed using the base form of the verb, with one critical exception: the third person singular.
Affirmative Sentences
| Person | Verb Form | Example |
| I / You / We / They | Base Form (Verb) | They live in the city. |
| He / She / It | Base Form + -s | She lives in the city. |
Negative Sentences (The Auxiliary Verbs)
We use the auxiliary verb do (or does for the third person singular) + not + base form. The main verb never takes -s in the negative form.
I / You / We / They do not (don’t) live in Paris.
He / She / It does not (doesn’t) live in Paris.
Questions (Interrogative Form)
We start with Do (or Does) + Subject + base form of the main verb.
Do you understand the problem?
Does she speak French?
Usage: When to Use the Present Simple (4 Key Rules)
The Present Simple is used for stable and permanent situations — not for actions happening at the moment of speaking.
Negative Sentences (The Auxiliary Verbs)
Use it to describe actions that happen regularly or repeatedly.
I go to the gym three times a week. (Routine)
She eats breakfast every morning. (Habit)
General Facts and Truths
Use it for things that are generally accepted as true or scientific facts.
Water freezes at 0 degrees Celsius. (Fact)
The sun rises in the east. (Scientific Truth)
Scheduled Events (Timetables)
Use it for scheduled events in the near future (transport, cinema, school).
The bus leaves at 7:30 tomorrow morning. (Fixed Schedule)
The film starts in ten minutes. (Timetable)
States (State Verbs)
Use it to describe feelings, thoughts, and states of being (verbs like know, believe, understand, love, hate, need, seem).
She doesn’t believe his story. (Opinion/State)
I know the answer to that question. (Thought/State)
Key Rules: The Third Person Singular (-s, -es, -ies)
This is the most common mistake. The rule applies only to affirmative sentences with He, She, or It.
The Basic Rule: Add -s
Most verbs: Work – works, Play – plays
The -es Rule (When to Add -es)
If the verb ends in a sibilant sound, you add -es. This applies to verbs ending in -ss, -sh, -ch, -x, -o, or -z.
| Ending | Example | He/She/It Form |
| -sh | wash | washes |
| -ch | watch | watches |
| -o | go | goes |
The -y Rule (When to Change to -ies)
Consonant + y: Change the y to i and add -es (e.g., try – tries, study – studies).
Vowel + y: Just add -s (e.g., play – plays, buy – buys).
Time Expressions (Signal Words)
The following words and phrases are strong indicators that the Present Simple is required:
Frequency: always, usually, often, sometimes, rarely, never.
Routine: every day/week/month/year, on Mondays/weekends, once a week.
Simple Time: in the morning, at night, at the weekend.
