French Lesson: Expressing Doubt with 'sembler', 'paraître', and 'avoir l'air'
Learn to express doubt using French verbs and expressions that focus on appearance: sembler, paraître, avoir l'air, and more.

In French, expressing doubt or uncertainty often involves verbs that mean 'to seem' or 'to appear'. These are different from phrases like 'peut-être' or 'je ne suis pas sûr' because they focus on how something looks or appears, rather than on your personal uncertainty. This lesson will teach you how to use 'sembler', 'paraître', 'avoir l'air', and related expressions to convey doubt based on appearance. You'll learn to construct sentences like 'Il semble peu probable' (It seems unlikely) and 'Elle a l'air d'être fatiguée' (She looks tired). We'll cover the grammar, common pitfalls, and provide practice to help you use these expressions naturally.
By the end, you can…
- use 'sembler', 'paraître', and 'avoir l'air' to express doubt based on appearance.
- distinguish between these expressions and other uncertainty phrases.
- construct sentences with the correct preposition and mood after these verbs.
Listen once. Try it slowly. Then say it without looking.

It seems unlikely that...
eel sahm-bluh puh pro-bahbl kuh
Followed by the subjunctive mood: 'Il semble peu probable qu'il vienne.'
Elle a l'air d'être en retard.
She looks like she's late.
el ah lair det-ruh ahn ruh-tar
'Avoir l'air' is very common in spoken French. 'D'être' is optional but common.
Cela paraît impossible.
That appears impossible.
suh-lah pah-reh eh(n)-po-seebl
'Paraître' is slightly more formal than 'sembler' or 'avoir l'air'.
Il semble que oui.
It seems so.
eel sahm-bluh kuh wee
Used to agree tentatively. 'Il semble que non' means 'It seems not.'
J'ai l'impression que...
I have the impression that...
zhay lam-pre-syon kuh
Expresses a personal impression, similar to 'it seems to me.'

Useful pattern
The most common pattern is: subject + sembler/paraître/avoir l'air + adjective or noun. For example: 'Il semble content' (He seems happy), 'Elle paraît surprise' (She appears surprised), 'Ils ont l'air fatigués' (They look tired). When followed by a verb, 'sembler' and 'paraître' take 'de' + infinitive: 'Il semble savoir' (He seems to know), 'Elle paraît comprendre' (She appears to understand). With 'avoir l'air', you can also use 'd' + infinitive: 'Elle a l'air de comprendre' (She seems to understand). Note that 'sembler' and 'paraître' can also be used impersonally: 'Il semble que...' (It seems that...), which requires the subjunctive.
When to use it
Use these expressions when you want to express doubt based on visual or sensory evidence, or when you want to soften a statement. For example, instead of saying 'Il est coupable' (He is guilty), you can say 'Il semble coupable' (He seems guilty), which leaves room for doubt. 'Avoir l'air' is the most colloquial and is often used in everyday conversation. 'Paraître' is more formal and literary. 'Sembler' is neutral and can be used in both spoken and written French. Be careful: 'paraître' can also mean 'to appear' in the sense of 'to become visible' or 'to be published', but context usually clarifies.
Listen to each line, then take one part and reply out loud.
Regarde, Paul a l'air fâché. Tu ne trouves pas ?
Look, Paul looks angry. Don't you think?ruh-gard, pol ah lair fah-shay. tew nuh troov pah ?Oui, il semble contrarié. Il paraît qu'il a eu une mauvaise nouvelle.
Yes, he seems upset. It appears he got some bad news.wee, eel sahm-bluh kon-tra-ryay. eel pah-reh keel ah uh oon moh-vez noo-vel.Cela semble peu probable, il était si joyeux ce matin.
That seems unlikely, he was so cheerful this morning.suh-lah sahm-bluh puh pro-bahbl, eel ay-tay see zhwah-yuh suh mah-tan.J'ai l'impression qu'il cache quelque chose.
I have the impression that he's hiding something.zhay lam-pre-syon keel kash kel-kuh shoz.A little context goes a long way
In French, 'avoir l'air' is extremely common in informal speech, while 'paraître' is more formal and often used in writing. 'Sembler' is versatile. In Quebec, 'avoir l'air' is also used, but you might hear 'sembler' more in formal contexts. When using 'il semble que', the subjunctive is required, which can be a challenge for learners. Also, note that 'paraître' can sometimes imply a misleading appearance, as in 'paraître' vs 'être'.
One thing to watch for
Using the indicative after 'il semble que' instead of the subjunctive.
Try this instead: After 'il semble que', use the subjunctive: 'Il semble qu'il soit malade' (It seems he is sick). However, in the negative or interrogative, the indicative is sometimes used: 'Il ne semble pas qu'il est malade' is acceptable in informal speech, but the subjunctive is preferred.
Your turn
Try answering out loud before checking a possible answer.
1Translate: 'It seems unlikely that she will come.'
Show a sample answer
Il semble peu probable qu'elle vienne.
This uses 'il semble peu probable que' + subjunctive 'vienne'. Alternatively, 'Il semble peu probable qu'elle viendra' is sometimes heard but less correct.
2What is the difference between 'Il semble triste' and 'Il a l'air triste'?
Show a sample answer
Both mean 'He seems sad', but 'avoir l'air' is more colloquial and based on appearance, while 'sembler' is more neutral.
Both are correct, but 'avoir l'air' is more common in spoken French. 'Sembler' can be used in both formal and informal contexts.
3Fill in the blank: 'Elle ___ d'être enceinte.' (looks like)
Show a sample answer
a l'air
'Elle a l'air d'être enceinte' is correct. 'Semble' would require 'Elle semble être enceinte' without 'de'.
Use 'sembler', 'paraître', and 'avoir l'air' to express doubt based on appearance. Remember the subjunctive after 'il semble que', and choose the right register: 'avoir l'air' for casual, 'paraître' for formal.
