On va commencer avec une question! La réponse à la fin.

To express need, there are many words you can use in French.

First, in general, it’s better not to use c’est nécessaire de to mean “it’s necessary to.”

We often just say C’est nécessaire to mean that something is (absolutely) necessary.

  • «Je n'achète que des vêtements de seconde main, et seulement si c'est nécessaire»

    “I only buy used clothes, and only if that’s absolutely necessary.”

Then you can say il est nécessaire de but it means more that something is essential or required, and it’s used more in writing.

  • Il est nécessaire de rester en forme

    Staying in shape is essential

To express “need,” you have three options

Il faut

Most of the time, you’ll use the verb falloir, when talking about something you need to do.

  • I need to go the bank

    Il faut que j’aille à la banque

Note that il faut que always calls for the subjunctive.

  • I need to go

    Il faut que je parte

  • You need to do a better job

    Il faut que tu fasses mieux ton travail

You might know how to use il faut, but do you know how to conjugate it in the past and in the future?

In the past

Il fallait / il a fallu

  • I needed to go to Dallas

    Il a fallu que j’aille à Dallas

  • It was a difficult situation. You had to be alert
    C’était une situation difficile. Il fallait être alerte

In the future

Il va falloir / il faudra

  • I'll have to change my vocabulary a bit
    Il va falloir changer un peu mon vocabulaire

  • We’ll need to go soon!
    Il va falloir y aller bientôt!

  • We will need years to measure the real effect of the Brexit

    Il faudra des années pour mesurer l'effet réel du Brexit

Devoir

Il faut tends to mean “I need” but the verb devoir tends to be translated as “must,” or “have to.” It usually implies an obligation.

  • Ils doivent déposer leur demande avant le 4 août
    They need to send their application before August 4th (they must)

  • Je dois aller travailler
    I need to go to work (I must go to work)

Avoir besoin de

Avoir besoin de is often a synonym for il faut. It more common to use it when you “need something,” or when the need is emotional.

  • J’ai besoin de te parler

    I need to talk to you (more emotional)

  • Il faut que je te parle
    I need to talk to you (more urgent, more factual, less emotional)

  • J’ai besoin de café
    I need coffee. (Need something)

  • Il faut que j’achète du café
    I need to buy coffee

  • Merci, mais je n’ai besoin de rien
    Thank you, but I don’t need anything

  • J’ai besoin de changer d’air
    I need a change of scenery

Note

  • J’ai besoin de is followed by a noun or a verb

  • Il faut que is followed by a verb

La réponse à la question…

  • On peut dire je dois partir ou bien il faut que parte. On ne dit pas j’ai besoin de partir.

  • Je dois partir est une obligation.

  • Il faut que je parte est la phrase la plus courante! Et on dit aussi: Il faut que je m’en aille! Ou encore je dois y aller ou je vais devoir y aller!
