Historical Context & Motivation
Humans have always needed to compare things—who is taller, what is faster, which option is better. In every language, speakers develop specific grammatical patterns to express these comparisons. French inherited its comparison structures from Latin, which used distinct word endings (suffixes) to show whether something was "more," "less," or "equally" a certain quality. Over centuries, as Latin evolved into the Romance languages, French replaced most of those suffixes with separate words placed around the adjective or adverb.
Understanding this evolution helps explain why French comparisons look the way they do today. Instead of changing the adjective itself (the way English adds "-er" to create "taller"), French typically keeps the adjective intact and wraps it in a small frame of words: plus...que, moins...que, or aussi...que. This pattern is elegant, predictable, and—once you see the logic—quite easy to master.
The key question this lesson addresses is straightforward: how do you take any French adjective or adverb and turn it into a comparison? Once you learn the three patterns, you will be able to compare people, places, things, and actions in a wide variety of everyday situations.
Core Principles & Definitions
French comparisons rely on a simple, repeatable formula. You pick a comparison word (plus, moins, or aussi), place it before the adjective or adverb, and close the comparison with que ("than" or "as") followed by the person or thing you are comparing to. The adjective itself does not change form—it only needs to agree in gender and number with the noun it describes, as usual.
Plus...que (More...than)
Moins...que (Less...than)
Aussi...que (As...as)
Que = The Bridge Word
Adjective Agreement Still Applies
Visual Explanation
The diagram below shows how French comparison sentences are assembled. Each colored segment represents one part of the sentence structure. Notice how the core formula remains constant across all three types—only the comparison word at the beginning changes.
As you can see in the diagram, the overall sentence architecture remains identical across all three comparison types. The subject comes first, then the verb être (or another linking verb), then the comparison word, then the adjective, then que, and finally the second element. The only variable that changes the meaning from "more" to "less" to "equal" is that single word before the adjective.
How the Structures Work
The Formulas
Although French comparisons are not "math," they follow predictable formulas that you can memorize and apply just like equations. Below are the three core formulas along with the key details about each one.
Stress Pronouns After Que
When the second element of the comparison is a pronoun, French uses stress pronouns (also called disjunctive pronouns) after que: moi, toi, lui, elle, nous, vous, eux, elles. You would say plus grand que moi (taller than me), not *plus grand que je. This is one of the most common spots where beginners slip up, so keep it in mind.
Detailed Breakdown & Adjective vs. Adverb Comparisons
So far, most examples have compared adjectives (describing nouns). However, the same three structures work perfectly with adverbs (describing verbs). For instance, you can say Il court plus vite que moi (He runs faster than me), where vite is an adverb modifying the verb courir. The diagram below shows how adjective and adverb comparisons line up side by side.
| Comparison Type | French Structure | English Equivalent |
|---|---|---|
| Superiority | plus + adj./adv. + que | more...than / -er...than |
| Inferiority | moins + adj./adv. + que | less...than |
| Equality | aussi + adj./adv. + que | as...as |
Worked Example
Let's walk through the process of building a comparison sentence from scratch. Suppose you want to say: "My car is faster than your car."
Common Errors & How to Avoid Them
Even though the comparison formulas are straightforward, certain mistakes pop up repeatedly among French 1 learners. The table below lists the most frequent errors alongside the correct forms, so you can train your eye—and your ear—to catch them before they become habits.
| Common Mistake | Correct Form | Why It's Wrong |
|---|---|---|
| *Elle est plus bon que lui. | Elle est meilleure que lui. | "Bon" has an irregular comparative: meilleur(e). Never say plus bon. |
| *Il est plus grand que je. | Il est plus grand que moi. | After que, use stress pronouns (moi, toi, lui...), not subject pronouns. |
| *Elle est aussi grande comme lui. | Elle est aussi grande que lui. | The bridge word is always que, not comme, in these structures. |
| *Les filles sont plus grand que les garçons. | Les filles sont plus grandes que les garçons. | The adjective must still agree. Grandes = feminine plural to match les filles. |
| *Il mange plus vite de moi. | Il mange plus vite que moi. | Use que (not de) after adjective/adverb comparisons. |
Connection to Advanced Comparison Structures
The plus/moins/aussi...que structures you learned in this lesson are the foundation for more advanced comparison topics you will encounter as your French progresses. The table below previews how today's "comparatif" connects to tomorrow's grammar.
| What You Know Now (Comparatif) | What's Coming Next (Superlatif & Beyond) |
|---|---|
| plus grand que (taller than) | le plus grand (the tallest) — the superlative adds a definite article |
| moins cher que (less expensive than) | le moins cher (the least expensive) — superlative of inferiority |
| Comparing adjectives/adverbs | Comparing nouns with plus de / moins de / autant de...que (more of, less of, as much of) |
| Regular comparisons | Irregular forms: bon → meilleur, bien → mieux, mauvais → pire |
Mastering the three basic comparison patterns gives you a reliable template that expands naturally into these more complex forms. When you eventually study the superlative or compare quantities, you will notice that the core logic—a framing word, the quality, and que—remains consistent. Building a strong foundation now will make those later topics feel like natural extensions rather than entirely new rules.
Practice Problems
Lesson Summary
French comparisons use three predictable structures that all follow the same pattern. To say something has more of a quality, use plus + adjective/adverb + que (superiority). To say something has less of a quality, use moins + adjective/adverb + que (inferiority). To say two things share a quality equally, use aussi + adjective/adverb + que (equality). The word que always introduces the second element of the comparison and translates as "than" or "as" depending on context.
Remember three critical details: adjectives must still agree in gender and number with the subject; after que, use stress pronouns (moi, toi, lui, elle, etc.) instead of subject pronouns; and bon → meilleur(e) is an irregular form—never say plus bon. These three comparison structures are the gateway to the French superlative and to comparing quantities, so mastering them now sets you up for success in future grammar topics.
