'Tomber' for getting ill, falling in love and breaking down

In French, a handful of everyday changes of state are expressed with the verb tomber, literally to fall. You do not get ill, you fall ill: tomber malade. You fall in love, just as in English: tomber amoureux. A car does not break down, it falls into breakdown: tomber en panne.

English speakers tend to trip over this in two ways. First, English uses different verbs here (get, fall, break), so learners reach for devenir or a word-for-word translation instead. Second, once they notice the pattern, they are tempted to use tomber with any state at all, which French does not allow. These are fixed expressions, not a free rule.

How it works

Each expression describes the moment you move into a state, not the state itself. The state is described with être. Tomber describes the change:

  • être malade = to be ill, tomber malade = to fall ill
  • être amoureux = to be in love, tomber amoureux = to fall in love
  • être en panne = to be out of order, tomber en panne = to break down

The change is often sudden, but it does not have to be. What matters is that something starts. Because tomber is a verb of movement, it takes être in the passé composé, and the past participle agrees with the subject: elle est tombée, ils sont tombés.

Il est malade depuis lundi.
(He has been ill since Monday.)
Il est tombé malade lundi.
(He fell ill on Monday.)
The words

Tomber malade is the standard way to say that someone gets ill. It works for a single event and for a habit.

Elle est tombée malade pendant les vacances.
(She fell ill during the holidays.)
Mon fils tombe souvent malade en hiver.
(My son often gets ill in winter.)

Tomber amoureux matches English closely, but remember that amoureux is an adjective. It agrees with the subject: amoureuse, amoureux, amoureuses. The person you fall for is introduced with de. In casual speech you will also hear avec.

Ils sont tombés amoureux à Paris.
(They fell in love in Paris.)
Je suis tombée amoureuse de mon voisin.
(I fell in love with my neighbour.)

Tomber en panne is used for machines and vehicles that stop working: cars, lifts, computers, washing machines.

La voiture est tombée en panne sur l'autoroute.
(The car broke down on the motorway.)
Mon ordinateur est tombé en panne hier soir.
(My computer stopped working last night.)
Watch out

Do not build new combinations. You cannot say tomber fatigué or tomber triste. For most other changes of state, French uses devenir or a reflexive verb, such as se fatiguer or s'énerver. Beyond the three expressions above, you will also meet tomber d'accord (to come to an agreement) and tomber enceinte (to get pregnant). Learn them as set phrases too.

Never use avoir in the past tense: j'ai tombé malade is a very common mistake. The correct form is je suis tombé malade.

Nous sommes tombés en panne au milieu de nulle part.
(We broke down in the middle of nowhere.)

As this example shows, people may say nous sommes tombés en panne when their car breaks down. This is normal in spoken French, but it still refers to the vehicle, not to the people. Finally, keep this use apart from ordinary tomber (to fall over, to drop), which describes a physical fall.

Summary

To describe the moment someone gets ill, falls in love or a machine breaks down, use tomber + the state: tomber malade, tomber amoureux, tomber en panne. Use être both for the state itself and as the auxiliary in the past tense (elle est tombée malade), and make the participle agree. Treat these as fixed expressions. Do not attach tomber to other adjectives.
