Historical Context & Motivation
Every language needs glue — small words that hold ideas together and show how they relate. In French, words like et, mais, parce que, and donc have served this purpose for centuries. These connectors — known formally as conjonctions de coordination and conjonctions de subordination — evolved from Latin roots as the French language took shape over more than a thousand years. Understanding their origins helps you see that connectors are not arbitrary grammar rules; they reflect how humans naturally organize thought.
Without connectors, you would write sentences like: J'aime le français. Le français est difficile. That sounds robotic. The central question this lesson addresses is: how do you use et, mais, parce que, and donc to combine those ideas into smooth, connected sentences that sound natural and express clear relationships between thoughts?
Core Principles & Definitions
A connector (also called a conjunction or mot de liaison) is a word or short phrase that joins two ideas and signals the relationship between them. Before diving into each connector, it helps to understand four foundational principles that govern how they work in French.
Addition — et
Contrast — mais
Cause — parce que
Consequence — donc
Visual Explanation — The Connector Map
Look at how each connector creates a different kind of bridge between the two boxes. When you write or speak, choosing the right connector tells your audience exactly how your ideas connect. Using et says "here's more of the same." Using mais warns "this next part might surprise you." Using parce que promises "here's the reason." And using donc announces "here's what follows logically." Mastering these four signals gives your French a natural, coherent rhythm.
How Each Connector Works — Grammar & Placement
Coordinating vs. Subordinating
French connectors fall into two grammatical categories. Coordinating conjunctions (conjonctions de coordination) join two elements of equal grammatical status — two independent clauses, two nouns, two adjectives. Et, mais, and donc are all coordinating conjunctions. Subordinating conjunctions (conjonctions de subordination) introduce a dependent clause that cannot stand alone. Parce que is a subordinating conjunction because the clause it introduces depends on the main clause for meaning.
Placement Rules
For et, the connector sits directly between the two elements it joins: Marie et Paul étudient. No comma is needed before et when joining just two items. However, in a list of three or more, commas separate all items except the last pair: Marie, Paul et Sophie. Note that French does not use the Oxford comma.
For mais, a comma typically precedes it when joining two independent clauses: Je veux sortir, mais il pleut. This comma signals a pause that mirrors the shift in meaning.
For parce que, the connector introduces the reason clause, which can come after or before the main clause. When it follows, no comma is needed: Je suis fatigué parce que j'ai couru. When the reason clause comes first (less common), use a comma: Parce qu'il pleut, je reste ici. Also note the elision rule: before a vowel or silent h, parce que becomes parce qu'.
For donc, placement is flexible. It often appears after the subject or between the two clauses: Il pleut, donc je prends un parapluie or Je suis donc en retard. When placed between clauses, a comma usually precedes it.
Sentence Patterns & Classification
Each connector creates a distinct sentence pattern. Recognizing these patterns helps you both construct and interpret French sentences with confidence. The diagram below illustrates the structural template for each connector, and the table that follows provides a quick-reference classification.
| Connector | Type | Function | Comma Before? | Elision? |
|---|---|---|---|---|
| et | Coordinating | Addition | No (usually) | No |
| mais | Coordinating | Contrast | Yes | No |
| parce que | Subordinating | Cause / Reason | No (after main clause) | Yes → parce qu' |
| donc | Coordinating | Consequence / Result | Yes (between clauses) | No |
Worked Example — Building a Connected Paragraph
Let's take five short, disconnected French sentences and transform them into a fluent paragraph by choosing the right connectors. This mirrors what you would do in a writing assignment or speaking exercise.
Common Errors & How to Avoid Them
Even when you know the four connectors, certain mistakes come up again and again for French 2 learners. The table below lists the most frequent errors alongside the correct usage and an explanation of why the mistake happens.
| Common Error | Correct Version | Why It Goes Wrong |
|---|---|---|
| *parce que il est fatigué | parce qu'il est fatigué | Forgetting elision before a vowel. English "because" never changes form, so learners forget this French rule. |
| *Je suis fatigué car je travaille. (when parce que is needed) | Je suis fatigué parce que je travaille. | Confusing car (more formal/written) with parce que (spoken & written). At this level, stick to parce que. |
| Overusing et for every connection | Vary connectors: mais, donc, parce que | English speakers default to "and" in speech. In French writing, varied connectors show clearer logic. |
| *Mais, j'aime le chocolat. (starting a sentence) | Attach to the previous clause or restructure. | In formal French, coordinating conjunctions should link elements within a sentence, not start one. |
| Using donc where alors fits better | Both work, but donc is more logical; alors is more narrative. | The difference is subtle. Donc = logical consequence; alors = "then" in storytelling. For now, donc is your go-to. |
Connection to Advanced Connectors
The four connectors you are learning now form the foundation for a much larger family of linking words that you will encounter in French 3 and beyond. As your writing becomes more sophisticated, you will want to express finer shades of meaning — slight concession, alternative possibilities, temporal sequence, and more. The table below previews how each basic connector has an advanced counterpart or expansion.
| Basic Connector | Advanced Equivalents | Nuance Added |
|---|---|---|
| et (and) | de plus, en outre, également | More formal addition; used in essays and speeches to layer arguments. |
| mais (but) | cependant, pourtant, néanmoins, toutefois | Softer or stronger contrasts; pourtant implies surprise, néanmoins is very formal. |
| parce que (because) | car, puisque, étant donné que, comme | Car is literary; puisque implies the reason is already known; comme introduces reason at the start. |
| donc (so) | par conséquent, ainsi, c'est pourquoi, alors | Par conséquent is academic; c'est pourquoi introduces a sentence-level conclusion. |
For now, focus on mastering et, mais, parce que, and donc. Once these feel automatic, you will be ready to swap in the advanced versions for more polished, nuanced expression in essays and oral presentations.

Lesson Summary
French relies on four essential connectors to transform choppy sentences into coherent, flowing text. Et (and) adds information of equal weight. Mais (but) signals a contrast or unexpected twist. Parce que (because) introduces a reason and is the only subordinating conjunction of the four — remember the elision rule (parce qu' before a vowel). Donc (so / therefore) states a logical consequence or result.
When writing or speaking, choose your connector based on the logical relationship between ideas: addition, contrast, cause, or consequence. Pay attention to comma placement (before mais and donc when joining clauses) and vary your connectors to keep your French sounding natural and mature. These four words are the foundation for the richer set of advanced linking words — like cependant, pourtant, puisque, and par conséquent — that you will encounter in future courses.
