Logical connectors (cause, consequence, goal, opposition)
B1 Les relations logiques (cause, conséquence, but, opposition) 46 / 52
In short
Logical connectors are the words that link two ideas and show how they relate: a cause (why), a consequence (result), a goal (aim), or an opposition (contrast). The key is to pick the connector that matches the relationship, and to know whether it joins two clauses or introduces a noun or an infinitive.
The rule
Each connector belongs to a family. Learn the family first, then note the grammar each one requires: some join two full clauses (Je reste parce que j’ai le temps), some introduce a noun (Grâce à toi…), and some introduce an infinitive (pour partir, afin de partir).
Cause - saying why
- parce que = “because”; the everyday answer to pourquoi ? It joins two clauses and can start the answer: Pourquoi tu pars ? - Parce que je suis fatigué.
- car = “for / because”; a bit more written, gives a justification. It never starts a sentence and cannot answer pourquoi ? directly: Je pars, car je suis fatigué.
- puisque = “since / seeing that”; the cause is already known or obvious to the listener: Puisque tu es là, aide-moi.
- grâce à = “thanks to”; introduces a noun and marks a positive cause: Grâce à ton aide, j’ai réussi. (à cause de marks a negative cause: à cause de la pluie.)
Consequence - the result
- donc = “so / therefore”; the logical result: Je pense, donc je suis.
- alors = “so / then”; more spoken, often a reaction: Il pleut, alors je reste.
- c’est pourquoi = “that is why”; introduces a clearly stated conclusion: Il n’a pas révisé ; c’est pourquoi il a échoué.
Goal - the aim
- pour + infinitive = “(in order) to”: Je travaille pour gagner ma vie.
- afin de + infinitive = “in order to”; the same idea, slightly more formal: Il note tout afin de ne rien oublier.
- Only pour can also introduce a noun: un cadeau pour ton frère; afin de is always followed by an infinitive. When the two subjects differ, French switches to pour que / afin que + subjunctive (see Lesson 38).
Opposition and concession - the contrast
- mais = “but”; the basic contrast (A2): C’est petit mais confortable.
- alors que = “whereas / while”; contrasts two facts at once: Lui aime le froid, alors que moi je déteste ça.
- malgré = “despite / in spite of”; introduces a noun, not a clause: Malgré la pluie, on est sortis. (For “despite the fact that” + clause, French uses bien que + subjunctive, B2.)
Concession is a special opposition: the second idea is unexpected given the first (Il pleut, mais on sort quand même). The strongest concessive links - bien que, quoique - govern the subjunctive and belong to Lesson 38.
Forms & patterns
| Family | Connector | What follows | Register |
|---|---|---|---|
| Cause | parce que | clause | neutral |
| Cause | car | clause (never first) | written |
| Cause | puisque | clause (known cause) | neutral |
| Cause | grâce à | noun / pronoun | neutral |
| Consequence | donc | clause | neutral |
| Consequence | alors | clause | spoken |
| Consequence | c’est pourquoi | clause | written |
| Goal | pour | infinitive / noun | neutral |
| Goal | afin de | infinitive | formal |
| Opposition | mais | clause / word | neutral |
| Opposition | alors que | clause | neutral |
| Opposition | malgré | noun / pronoun | neutral |
grâce à contracts with the definite article, exactly like the preposition à (see Lesson 04):
| + article | Form | Example |
|---|---|---|
| le | grâce au | grâce au soleil |
| la | grâce à la | grâce à la chance |
| l’ | grâce à l’ | grâce à l’aide |
| les | grâce aux | grâce aux voisins |
Examples
| Français | English |
|---|---|
| Je reste à la maison parce qu’il pleut. | I am staying home because it is raining. |
| Il faut partir, car il est tard. | We must leave, for it is late. |
| Puisque tu connais la route, tu conduis. | Since you know the way, you drive. |
| Grâce à ses conseils, j’ai trouvé un travail. | Thanks to his advice, I found a job. |
| La route est bloquée, donc on fait demi-tour. | The road is blocked, so we turn back. |
| Elle a beaucoup travaillé ; c’est pourquoi elle a gagné. | She worked hard; that is why she won. |

| Il sort malgré le froid, alors que son frère reste. | He goes out despite the cold, whereas his brother stays. |
Common mistakes
- Car il est tard, je pars. -> Je pars, car il est tard. -
carcannot begin a sentence; put the main idea first. - À cause de ton aide, j’ai réussi. -> Grâce à ton aide, j’ai réussi. - use
grâce àfor a positive cause;à cause deis negative. - Malgré qu’il pleuve… -> Malgré la pluie… / Bien qu’il pleuve… -
malgrétakes a noun; a clause needsbien que+ subjunctive. - Je travaille pour que gagner ma vie. -> Je travaille pour gagner ma vie. - one subject ->
pour+ infinitive;pour queneeds two subjects + subjunctive. - Parce que la pluie, je reste. -> À cause de la pluie, je reste. -
parce queneeds a clause; before a bare noun useà cause de. - Il est malade, alors que il ne vient pas. -> Il est malade, donc il ne vient pas. - a result uses
donc;alors quemarks contrast, not consequence.
Tips
- Two-word test: can you follow it with a full clause (subject + verb)? If yes,
parce que / puisque / alors quework; if only a noun follows, reach forgrâce à / à cause de / malgré. parce queanswers pourquoi ? on its own;carnever can - keepcarinside a sentence.- Goal with one subject =
pour / afin de+ infinitive. Two different subjects flips topour que / afin que+ subjunctive (Lesson 38). donc= cool logical “therefore”;alors= warmer spoken “so, then”. Both are fine in conversation.grâce à= good outcome,à cause de= bad outcome - the grammar is identical, only the flavour changes.- Elision: parce que becomes parce qu’ before a vowel (parce qu’il, parce qu’elle).
