A small but very frequent group of French verbs obligatorily takes de between the verb and its noun complement. Se souvenir doesn't just take a direct object the way English remember does — it takes de and then the noun: je me souviens *de mon enfance. *Avoir besoin doesn't take a direct object either — j'ai besoin *de toi. The *de is not optional and not stylistic; it is a structural part of the verb. Drop it, and the sentence becomes ungrammatical, or — worse — changes meaning into something you didn't intend.
This page lists the verbs that take de + noun complement, shows how the de interacts with pronouns (replaced by en for things, kept with tonic pronouns for people), and explains the dont relative pronoun that replaces de + noun in relative clauses. By B1 you should treat these verb-preposition pairs as inseparable units.
Why "de" is structural, not optional
In English, remember is a transitive verb — it takes a direct object: I remember my childhood. In French, the equivalent verb se souvenir requires de: je me souviens *de mon enfance. The *de is part of the verb's basic syntax, the same way of is structurally required after think in English: I'm thinking of you, not I'm thinking you.
Because the de is structural, it appears even in casual speech, even in fast-paced conversation, even when it's the only difference between a grammatical sentence and an ungrammatical one. There is no register where you can drop it.
Je me souviens encore de notre premier voyage à Lyon.
I still remember our first trip to Lyon.
On a vraiment besoin de toi à la réunion ce soir.
We really need you at the meeting tonight.
Mes enfants ont peur des araignées, c'est terrible.
My kids are afraid of spiders, it's awful.
The high-frequency list
These are the verbs that you must learn as inseparable from de. The list isn't huge but every item is everyday vocabulary.
| Verb | Meaning | Example |
|---|---|---|
| se souvenir de | remember | Je me souviens de toi. |
| se rappeler | remember (no de) | Je me rappelle ton nom. |
| avoir besoin de | need | J'ai besoin d'aide. |
| avoir peur de | be afraid of | Il a peur du noir. |
| avoir envie de | want, feel like | J'ai envie d'un café. |
| avoir honte de | be ashamed of | Elle a honte de son accent. |
| parler de | talk about | On parle de toi. |
| discuter de | discuss | On discute de politique. |
| se moquer de | mock, make fun of | Il se moque de moi. |
| profiter de | take advantage of, enjoy | Profite du soleil ! |
| dépendre de | depend on | Ça dépend de toi. |
| se servir de | use | Sers-toi de la fourchette. |
| s'occuper de | take care of, deal with | Je m'occupe des enfants. |
| se rendre compte de | realize | Tu te rends compte du problème ? |
| changer de | change (object) | J'ai changé d'avis. |
| manquer de | lack, miss | On manque de temps. |
| se plaindre de | complain about | Il se plaint du bruit. |
| se passer de | do without | Je peux me passer de café. |
| rêver de | dream of | Je rêve d'une maison. |
| se méfier de | distrust, beware of | Méfie-toi de lui. |
| s'approcher de | approach | Approche-toi du feu. |
| s'éloigner de | move away from | Éloigne-toi du bord. |
| rire de | laugh at | Il rit de tout. |
The crucial trap: se rappeler also means "remember", but it takes a direct object without de. Je me rappelle ton nom, not je me rappelle de ton nom (though this last form is now widely used in colloquial speech and tolerated). For exam contexts, distinguish them carefully.
Tu te souviens de l'été où on est allés en Italie ?
Do you remember the summer we went to Italy?
Je me sers d'un dictionnaire bilingue pour les mots techniques.
I use a bilingual dictionary for technical words.
Elle s'occupe des enfants pendant que je travaille.

Do you realize how lucky you are?
Je peux me passer de viande, mais pas de café.
I can do without meat, but not without coffee.
"Changer de" — change which noun?
Changer de deserves its own note because it works differently from English change. Changer de + noun means switch / replace:
- changer de voiture — get a new car
- changer d'avis — change one's mind
- changer de travail — change jobs
- changer de chemise — change one's shirt
Without the de, changer + direct object means alter what already exists:
- changer la voiture — modify the (same) car
- changer le monde — change the world
This distinction is real and learners regularly conflate the two. Je veux changer ma voiture means "I want to modify my car"; je veux changer de voiture means "I want to get a new car".
J'ai changé d'avis, finalement je viens avec vous.
I've changed my mind — actually I'm coming with you.
Il faut changer de train à Lyon Part-Dieu.
You have to change trains at Lyon Part-Dieu.
Pronoun replacement: en for things, de + tonic for people
When the noun after de is replaced by a pronoun, French splits inanimate vs animate complements.
Things (inanimate) → en
The clitic en replaces de + noun when the noun refers to a thing or an idea. En sits in front of the verb just like other object pronouns.
- J'ai besoin de ton aide. → J'*en ai besoin.*
- Il parle de ses vacances. → Il *en parle.*
- On profite du soleil. → On *en profite.*
- Je me sers d'un dictionnaire. → Je m'*en sers.*
Tu as encore besoin de ce dossier ? — Non, je n'en ai plus besoin.
Do you still need that file? — No, I don't need it anymore.
On a parlé du nouveau projet ? — Oui, on en a parlé hier.
Have we talked about the new project? — Yes, we talked about it yesterday.
People (animate) → de + tonic pronoun
When the noun after de is a person, French does not use en. Instead it keeps de and follows it with a tonic pronoun (moi, toi, lui, elle, nous, vous, eux, elles).
- Je parle de Marie. → Je parle *d'elle.*
- On se moque de Pierre. → On se moque *de lui.*
- Elle a peur de ses parents. → Elle a peur *d'eux.*
- Tu te souviens de moi ? — yes, with tonic moi, not m'en souviens.
Tu te souviens de Pierre ? — Oui, je me souviens très bien de lui.
Do you remember Pierre? — Yes, I remember him very well.
Tu as besoin de tes parents pour ça ? — Non, je n'ai pas besoin d'eux.
Do you need your parents for that? — No, I don't need them.
Dont — the relative pronoun for de + noun
In a relative clause, de + noun is replaced by dont. Whenever a verb that takes de is the engine of the relative clause, dont is the connector.
- L'homme *dont je parle — the man I'm talking about (*parler de)
- La chose *dont j'ai besoin — the thing I need (*avoir besoin de)
- Le livre *dont je me souviens — the book I remember (*se souvenir de)
- Le problème *dont il s'occupe — the problem he's dealing with (*s'occuper de)
- Les amis *dont elle se moque — the friends she makes fun of (*se moquer de)
Dont is also used for genitive ("whose"): l'auteur dont le roman a gagné le prix. Both uses come from the same underlying de + noun pattern.
C'est exactement le livre dont j'ai besoin pour mon cours.
That's exactly the book I need for my class.
Le voyage dont je me souviens le mieux, c'est celui en Grèce.
The trip I remember best is the one in Greece.
Je n'aime pas la façon dont il parle de sa femme.
I don't like the way he talks about his wife.
Why English speakers find this hard
English doesn't use a preposition with most of the equivalent verbs. I remember it, I need it, I lack it — all transitive in English, taking a direct object. So English speakers reach for a transitive structure in French and produce je me souviens ça, j'ai besoin ça, je manque temps — all wrong.
The opposite trap also exists: English uses prepositions with some of these (think of, talk about, depend on) and beginners try to translate the preposition literally, sometimes getting it right (parler de matches talk about) and sometimes getting it wrong (English think about is penser à in French, not penser de). The match between English and French prepositions is loose and unreliable.
The cleanest fix is to memorize the verb together with its preposition as a single lexical unit: not se souvenir but se souvenir de; not avoir besoin but avoir besoin de. When you recall the verb, you recall the preposition with it.
Verbs that have de in some uses but not others
A few verbs change behavior depending on what follows them:
- manquer — manquer de qqch (lack) ≠ manquer qqn (miss someone, no de: Tu me manques = I miss you)
- profiter — profiter de qqch (take advantage of) — always de
- rire — rire de qqn/qqch (laugh at) ≠ rire (laugh, no complement)
- changer — changer de qqch (switch) ≠ changer qqch (alter)
- se rappeler — se rappeler qqch (no de in standard French) ≠ se souvenir de qqch (with de)
These pairs are worth a flashcard each — they catch every learner.
Tu me manques beaucoup depuis que tu es parti.
I miss you a lot since you left.
Cette ville manque de bons restaurants.
This city lacks good restaurants.
Common mistakes

I need your advice.
❌ Je parle Marie hier.
Incorrect — parler de qqn for 'talk about someone'.
✅ J'ai parlé de Marie hier.
I talked about Marie yesterday.
❌ Tu en as besoin ? — Non, je n'ai pas besoin de lui (when 'he' = a tool).
Incorrect — for an inanimate object, use en, not de + lui.
✅ Tu en as besoin ? — Non, je n'en ai pas besoin.
Do you need it? — No, I don't need it.
❌ Je me souviens d'elle ? — Oui, je m'en souviens (when 'her' = a person).

✅ Tu te souviens d'elle ? — Oui, je me souviens d'elle.
Do you remember her? — Yes, I remember her.
❌ J'ai changé ma voiture (when meaning 'got a new one').
Incorrect — changer + direct object means modify; for switching, use changer de.
✅ J'ai changé de voiture.
I got a new car.
Key takeaways
- The de after these verbs is structural — it cannot be dropped, and it changes the verb's meaning if removed.
- For things, replace de + noun with the clitic en. For people, keep de and use a tonic pronoun (de moi, de lui, d'elle, d'eux).
- Dont is the relative pronoun for de + noun — use it whenever the relative clause is built around a de-taking verb.
- Watch the trap pairs: se souvenir de vs se rappeler (no de), changer de (switch) vs changer (alter), manquer de (lack) vs manquer (miss someone).
- Memorize each verb as a unit with its preposition. Se souvenir de, avoir besoin de, profiter de — never as separate words.

- De vs À with Verbs Before an InfinitiveA2 — When one French verb is followed by another in the infinitive, the link between them is either nothing, the preposition de, or the preposition à. The choice is largely arbitrary and must be memorised verb by verb — but there are patterns and tendencies that make the lists learnable.
- À vs De avec les Verbes + InfinitifA2 — Why French verbs link to a following infinitive with à, with de, or with nothing at all — the verb-by-verb pattern that has no clean rule but a manageable list of frequencies you can memorize.

- Le Pronom EnA2 — En is the adverbial pronoun French uses to replace de + thing, partitive du/de la/des + noun, quantifiers, and de + place of origin. Why English has no equivalent, what en covers (some / any / of it / about it / from there), and the crucial rule that quantifiers stay behind when en is used.
- Les Propositions Relatives: structuresB1 — French relative clauses are built around a fixed inventory of relative pronouns — qui, que, dont, où, lequel — each chosen by the syntactic role of the relativized element. Unlike English, French never lets you drop the relative, and the past participle agrees with a preceding direct object via que.
- Préposition Manquante ou Mauvaise après VerbesA2 — The preposition you put after a French verb often differs from the English equivalent — sometimes adding one English doesn't have, sometimes dropping one English requires.
