SECTION 1
Historical Context & Motivation
Every language needs a way to say "this one" or "that one," and French is no exception. Demonstratives are words that let you point to specific people, objects, or ideas — like aiming a spotlight at exactly what you want your listener to notice. In English, you rely on just four words: this, that, these, those. French, however, builds its demonstratives around a system of gender and number agreement that has evolved over more than a thousand years.
~100 CE • Latin Roots
~900 CE • Old French Simplification
~1400 CE • Middle French Stabilization
~1700 CE • Modern French System
Understanding this history helps you see why French demonstratives look the way they do today. The core question this lesson addresses is straightforward: how do you say "this," "that," "these," and "those" in French — and how do you choose the right form?
SECTION 2
Core Principles & Definitions
In French, the equivalent of "this" or "that" placed before a noun is called a demonstrative adjective (un adjectif démonstratif). Unlike English, where "this" stays the same no matter the noun, French demonstrative adjectives must agree with the noun in both gender (masculine or feminine) and number (singular or plural). There are four forms you need to learn, plus two optional suffixes.

Visual Explanation — The Decision Flowchart
As the flowchart shows, the decision process is systematic. You only need to ask three questions about your noun: Is it plural? If singular, is it feminine? If masculine, does it start with a vowel or silent h? Each answer guides you to the correct form. The optional suffixes -ci and -là are added after the noun only when you need to emphasize "this one right here" versus "that one over there."
SECTION 4
How It Works — Agreement in Action
Let's look at exactly how agreement works with demonstrative adjectives. In French, an adjective doesn't just sit next to a noun — it changes its form to reflect the noun's properties. Demonstrative adjectives are no different, and the rules are actually simpler than for most other adjectives because the plural form is the same for both genders.
The Four Forms at a Glance
| Masculine | Feminine | |
|---|---|---|
| Singular | ce (ce stylo) / cet before vowel/silent h (cet écran) | cette (cette chaise) |
| Plural | ces (ces stylos) | ces (ces chaises) |
Summary of all demonstrative adjective forms in French
Pronunciation Notes
Ce is pronounced like "suh" — a short, unstressed syllable. Cet sounds like "set" and exists purely to avoid the awkward pause that would occur if you said "ce ami." Cette sounds like "set" as well, though it's slightly longer in careful speech. Ces rhymes with the English word "say." When ces precedes a vowel, liaison occurs: ces‿amis is pronounced "say-zah-mee."
Adding -ci and -là for Precision
In everyday conversation, French speakers often use ce, cette, ces without any suffix, and context makes the meaning clear. However, when you need to contrast two items — "Do you want this shirt or that shirt?" — you attach -ci (from ici, meaning "here") or -là (meaning "there") directly to the noun with a hyphen: cette chemise-ci ou cette chemise-là ?
SECTION 5
Detailed Breakdown — Forms in Context
Now let's see every demonstrative form used in complete sentences so you can observe the agreement pattern in real French. Pay attention to how the demonstrative changes while the sentence structure stays the same.
Notice that cette is used for all feminine singular nouns, whether they start with a consonant (cette fille) or a vowel (cette école). The special form cet only applies to masculine singular nouns before a vowel sound. This is a common point of confusion, so keep it in mind.
SECTION 6
Worked Example — Describing a Classroom
Imagine you're in a French classroom, pointing things out to a classmate. You want to say: "This desk is big. That teacher is nice. These notebooks are blue. That student (male) over there is my friend." Let's translate each sentence step by step.
Translating Four Demonstrative Sentences
- 1
Step 1 — "This desk is big."
The French word for desk is le bureau (masculine singular, starts with a consonant). Since it's masculine singular beginning with a consonant, we use ce. "Big" is grand.Ce bureau est grand. - 2
Step 2 — "That teacher is nice."
Assume we're talking about a female teacher: la professeure (feminine singular). We use cette. "Nice" is gentille (feminine form). Since she's farther away, we can optionally add -là.Cette professeure(-là) est gentille. - 3
Step 3 — "These notebooks are blue."
The word for notebook is le cahier (masculine), but here it's plural: les cahiers. For any plural noun, we use ces. "Blue" in the plural masculine is bleus.Ces cahiers sont bleus. - 4
Step 4 — "That student over there is my friend."
The word for (male) student is l'élève — masculine singular, and it starts with a vowel. So we use cet (not ce). We add -là to emphasize "over there." "My friend" is mon ami.Cet élève-là est mon ami.

English vs. French Demonstratives — A Comparison
One of the trickiest parts of learning French demonstratives is un-learning your English habits. The two languages handle "this/that" in fundamentally different ways, and understanding those differences will help you avoid common errors.
| Feature | English | French |
|---|---|---|
| Number of basic forms | 4: this, that, these, those | 4: ce, cet, cette, ces |
| Gender agreement | None — "this" works for all nouns | Required — must match masculine or feminine |
| Distance built in? | Yes — "this" = near, "that" = far | Not by default — distance added with -ci / -là |
| Special vowel form | No | Yes — cet before masc. sing. vowel/silent h |
| Plural distinction | these (near) vs. those (far) | ces (both) — use -ci / -là if needed |

Connection to Advanced Grammar — Demonstrative Pronouns
The demonstrative adjectives you've learned today always appear with a noun. But what happens when you want to say "this one" or "that one" without repeating the noun? That's where demonstrative pronouns come in. You'll encounter these in French 2, but it's helpful to see the connection now.
| Feature | Demonstrative Adjectives (this lesson) | Demonstrative Pronouns (future lesson) |
|---|---|---|
| Function | Modifies a noun (placed before it) | Replaces a noun entirely |
| Forms | ce, cet, cette, ces | celui, celle, ceux, celles |
| Example | Ce livre est intéressant. | Celui-ci est intéressant. |
| Translation | This book is interesting. | This one is interesting. |
Demonstrative adjectives vs. demonstrative pronouns
For now, focus on mastering ce, cet, cette, ces — the adjective forms that always appear before a noun. Once you can use these confidently, the pronoun forms will feel like a natural next step, because they follow the same logic of gender and number agreement.

SUMMARY
Lesson Summary
Summary
French demonstrative adjectives let you point out specific people and objects, just like English "this," "that," "these," and "those." The four forms are ce (masculine singular before a consonant), cet (masculine singular before a vowel or silent h), cette (feminine singular), and ces (all plurals). Unlike English, French does not build distance into the demonstrative itself — you add the optional suffixes -ci (near) and -là (far) after the noun when you need to contrast proximity.
To choose the right form, follow three steps: check if the noun is plural (use ces), then check its gender (feminine → cette), and finally check whether a masculine noun starts with a vowel sound (cet) or a consonant (ce). Master these forms now, and you'll be well prepared for demonstrative pronouns (celui, celle, ceux, celles) in future lessons.
