Present Simple: General Truths and Facts

1 Concept

Not a Habit — a Permanent Truth

📘 Module 1 — Present Simple — a second, related core use

In Lesson 9 you learned that Present Simple describes habits — a repeated pattern belonging to a specific person. This lesson covers a close relative: general truths and facts — things that are permanently true, for everyone, not just a personal routine.

The key difference from a habit:

Habit — "She drinks coffee every morning." (her personal routine)
Fact — "A square has four sides." (true for everyone, always)

A habit and a fact use the exact same form, but for a different reason underneath. A habit is really a repeated action — each time she drinks her coffee is one complete event, and Present Simple compresses that repeated pattern into a whole, the way Lesson 7 described. A fact is different: "has four sides" isn't an action at all — nothing is happening. It's just a state that's continuously true. There's no "middle" of a state to zoom into, which is why facts — like opinions in Lesson 8 — almost never take "be" + -ing. Lesson 14 covers this in full.

2 Form Review

Quick Refresher: Base Form / -s Form

Exactly the same form as Lesson 9 — no new grammar to learn here:

Subject	Form	Example
Plural / general subjects	base form	Birds build nests.
Singular subjects (it, he, she)	-s / -es form	The Earth goes around the Sun.

Facts about a single thing ("the Earth", "water", "a triangle") need the -s form, exactly like "he" or "she" — this trips learners up because they don't think of "the Earth" as being like "he" or "she," but grammatically, it behaves the same way.

3 Facts About the Natural World

Science, Nature, and Geography

Scientific and natural facts are the clearest example of this use — permanently true, not tied to one time.

The Earth goes around the Sun.
The sun sets in the west.
Rivers travel toward the sea.
Plants grow toward light.
Whales live in the ocean.

Facts like these don't need a frequency word — the present simple by itself already signals "always true, no exceptions."

4 Facts About People & Things

Definitions and General Characteristics

This use also covers general definitions — statements about a whole category, not one specific individual.

A dictionary contains word definitions.
A week has seven days.
Airlines require a valid passport.
Libraries offer free books to the public.
Farmers sell vegetables at the market.
Museums hold historical objects.

Notice the subject in each sentence is a category ("a dictionary," "airlines," "museums"), not one specific individual doing something once. That's the signal you're dealing with a definition, not a habit.

5 Common Mistake

Don't Use the Progressive for Permanent Facts

Just like with habits, learners are often tempted to use "be" + -ing for facts, because the fact isn't literally happening at this exact second. But a permanent truth is never "in progress" — so it always needs the simple form.

✗ The Earth is going around the Sun.
✓ The Earth goes around the Sun. Why: this suggests something temporary or unusual is happening right now — but this is permanently true, every day, forever.

✗ Bees are producing honey.
✓ Bees produce honey. Why: this is a definition of what bees do as a species, not a description of one specific event happening now.

Quick test: if the sentence would still be true yesterday, today, and tomorrow, without any exception, it's a fact — and it needs the simple form.

7 Choose the Right Sentence

Apply What You Know

Read each question carefully. Select the sentence that matches the description.

Question 1 of 8

Select the correct sentence describing a permanent fact.

B is correct. A permanent fact needs the simple form, not the progressive (A). C is past tense, wrongly suggesting this is no longer true. D is perfect (Level 2).

Question 2 of 8

Select the sentence with the correct subject-verb agreement for a fact.

C is correct. "A soccer match" is singular, just like "he" or "she", so it needs the -s form: "has", not "have" (A).

Question 3 of 8

Select the sentence that correctly states a general definition.

C is correct. A definition of what banks do needs the simple form. A is progressive (suggests it's unusual or temporary); B is past; D is perfect (Level 2).

Question 4 of 8

Select the best test for recognizing a fact rather than a habit.

C is correct. A fact is permanently true for everyone, with no exception — that's what separates it from a personal habit (which belongs to one specific person, and often has a frequency word).

Question 5 of 8

Select the best explanation for why facts use the simple form.

B is correct. A fact isn't an action at all — it's a state that's simply, continuously true, so it never takes the progressive.

Question 6 of 8

Select the sentence with the correct subject-verb agreement for a singular subject.

C is correct. "A rectangle" is singular, just like "he" or "she," so it needs "has," not "have" (A).

Question 7 of 8

Select the sentence that correctly states a scientific fact.

D is correct. A permanent, general fact needs the simple form, not the progressive (A), past (B), or perfect (C).

Question 8 of 8

Select the best signal that a sentence is a general definition, not a description of one individual.

A is correct. A definition describes a whole category or type, not one specific person doing something once — that's what separates it from a personal habit or a one-time event.

8 Summary

Present Simple — General Truths and Facts A second core use of Present Simple: permanent truths and definitions — not actions, but states that are simply, continuously true.

General truths and facts — permanent, always-true statements about the world, science, or definitions.
Different from a habit: a fact is true for everyone, not just one person's routine, and needs no frequency word.
Subject-verb agreement: singular subjects like "the Earth" or "a triangle" take the -s form, just like "he" or "she."
Common mistake: never use the progressive for a fact — "The Earth goes around the Sun," not "is going."
Quick test: if it would still be true yesterday, today, and tomorrow, without exception, it's a fact.
