Début in French: Beginnings, and Not D'abord

English borrowed debut and narrowed it to a first public appearance: an album, a season, a performance. French kept the word much broader - it is simply the beginning of anything, including a film, a month, or a sentence. Meanwhile a second beginning-word sits nearby, and learners regularly reach for the wrong one.

Quick answer

The noun names a starting point: le début du film, le début du mois. The phrase au début places you at that point in time. What it does not do is order a list - that job belongs to d’abord, which means first of all and expects a second step to follow. Confusing the two produces sentences that are grammatical and slightly off.

Au début, je ne comprenais rien. → At the beginning, I understood nothing.

D’abord, on prépare les légumes. → First of all, we prepare the vegetables.

Meaning and usage: Au début against d’abord

One marks a period, the other marks a step. Au début looks back at an early phase and often contrasts with how things are now: au début, c’était difficile. D’abord opens a sequence and implies ensuite is coming: d’abord on mange, ensuite on sort. If nothing follows, d’abord leaves the sentence hanging.

Au début, c’était difficile, mais ça va mieux. → At first it was hard, but it is getting better.

D’abord on mange, ensuite on sort. → First we eat, then we go out.

Examples in context: The beginning words sorted

Each phrase has a job, and the table is quicker to internalise than four separate rules.

Which beginning you mean

French	Meaning	Expects
au début	At first, early on	A contrast later
d’abord	First of all	Ensuite, puis
dès le début	Right from the start	Emphasis
au début de	At the beginning of	A noun
débuter	To begin	A verb, formal

Dès le début, j’ai su que ça marcherait. → Right from the start, I knew it would work.

Nuance and register: The false friend in the other direction

The English borrowing kept only the performance sense, so son premier album is a debut album in English but simply a first album in French. To say a performer made their debut, French uses faire ses débuts - plural, and with the possessive. The plural is not optional here, which surprises English speakers using the singular loanword.

Elle a fait ses débuts à l’Opéra. → She made her debut at the Opera.

Il a débuté sa carrière à Lyon. → He began his career in Lyon.

Time expressions and the calendar

The noun is the standard way to divide a month or a year: début janvier means early January, and it needs no preposition at all. The same pattern gives fin mars for late March. These bare forms are extremely common in speech and writing, and they are more natural than any longer construction.

Je pars début janvier. → I am leaving in early January.

Le projet se termine fin mars. → The project ends in late March.

Common mistakes to avoid

Do not use au début to open a list, since sequences need d’abord. Do not use d’abord for an early period with nothing following it. Do not make the performance phrase singular, because French says ses débuts. And do not forget the accent on the noun, which is part of the spelling rather than an optional flourish.

Au début du film, on ne comprend rien. → At the beginning of the film, you understand nothing.

A memory tip for the pair

Picture a timeline against a list. Au début is a point near the left-hand end of a line: a period you can look back at. D’abord is the number one on a list, and lists have a number two. If you can point at a “then,” you want the list word. If you are describing how things were early on, you want the timeline word.

Le début de la réunion a été tendu. → The beginning of the meeting was tense.

Test the two beginnings

Choose before you translate. “At first I hated it” describes an early period, so the timeline phrase fits. “First, chop the onions” opens a recipe sequence, so the list word is right. “She made her debut in Paris” needs the plural phrase. “Early February” takes the bare noun with no preposition.

Nous nous verrons début février. → We will meet in early February.
