§ Don't confuse 'ralentir' with 'lent' or 'lentement'
Many English speakers learning French try to use 'lent' (slow, adjective) or 'lentement' (slowly, adverb) directly as a verb. Remember, 'ralentir' is already the verb you need. You wouldn't say "to slow" something as "to make something slow" in French using 'lent'.
Il ralentit la voiture. (He slows down the car.)
§ 'Ralentir' is often used reflexively
When you want to say something itself slows down, you'll often use the reflexive form 'se ralentir'. This is very common for things like traffic, a pace, or a process. If you just use 'ralentir' without 'se', it implies someone or something is actively slowing down something else.
- DEFINITION
- Use 'se ralentir' when the subject is slowing itself down.
La circulation se ralentit. (The traffic is slowing down.)
Il faut ralentir le rythme. (We need to slow down the pace.)
§ Conjugation issues: irregular verb
'Ralentir' is an -IR verb, but it's not a regular one. It follows the pattern of verbs like 'finir' (to finish), 'choisir' (to choose), and 'réussir' (to succeed), which are often called 'verbs of the second group'. This means that in the present tense, for 'nous', 'vous', and 'ils/elles', you'll see an '-iss-' appear.
Here's a quick reminder of the present tense:
- Je ralentis
- Tu ralentis
- Il/Elle/On ralentit
- Nous ralentissons
- Vous ralentissez
- Ils/Elles ralentissent
A common mistake is to conjugate it like a regular -ER verb or a completely irregular -IR verb. Pay attention to that '-iss-'!
§ Using 'ralentir' with 'de' for speed
When specifying by how much you're slowing down, or to what speed, you'll often use 'de'.
Il doit ralentir de 20 km/h. (He needs to slow down by 20 km/h.)
La voiture a ralenti de 100 à 80 km/h. (The car slowed from 100 to 80 km/h.)
Don't forget this little 'de' when specifying a decrease in speed or rate. It's a small word that makes a big difference in meaning.

This is the direct opposite of 'ralentir'.
While 'ralentir' is about speed, 'augmenter' is a general term for making something larger in quantity or intensity.
This is the adverbial opposite of 'lentement', related to speed.
بهراحتی اشتباه گرفته میشود
Often confused with 'diminuer' (to decrease) or 'réduire' (to reduce), as slowing down can be seen as a form of reduction.
'Ralentir' specifically means to lessen speed or make something move slower. 'Diminuer' and 'réduire' are broader terms for making something smaller in quantity, size, or intensity.
La voiture a dû ralentir à l'approche du virage. (The car had to slow down as it approached the turn.)
Sometimes confused with 'doucement' (softly/gently). While both can imply a lack of speed, 'doucement' emphasizes gentleness.
'Lentement' means slowly, focusing purely on speed. 'Doucement' means gently or softly, often referring to manner rather than just pace.
Elle marchait lentement dans le parc. (She walked slowly in the park.)
Can be confused with 'en retard' (late). 'Tard' is an adverb meaning late in time, while 'en retard' describes being behind schedule.
'Tard' refers to a late point in time (e.g., 'Il est tard' - It's late). 'En retard' means to be late for something specific (e.g., 'Je suis en retard' - I am late).
Nous avons mangé tard ce soir. (We ate late tonight.)
As an adjective, it means calm or quiet, but can be confused with 'tranquille' (peaceful/quiet). 'Calme' often implies a lack of agitation.
'Calme' refers to a state of being free from agitation or disturbance. 'Tranquille' suggests a more profound sense of peace and quiet, often implying serenity.
La mer était calme après la tempête. (The sea was calm after the storm.)
Can be confusing because it has multiple meanings like soft, sweet, gentle, or mild, depending on context.
The meaning of 'doux' depends heavily on the noun it modifies. It can describe texture (soft), taste (sweet), temperament (gentle), or weather (mild).
Ce pull est très doux. (This sweater is very soft.) Le temps est doux aujourd'hui. (The weather is mild today.)
