Commencer: the hook under the c, and what it is doing there.

Commencer means “to start”, and it is regular apart from one accent that beginners often assume is decorative. The cedilla — the little hook under ç — is load-bearing. Without it, commencons would be read “ko-man-KOHN”. With it, the c stays an s sound, which is what the verb actually is.

Présent — where the cedilla appears

Five regular forms and one with a hook. Only nous takes it, for exactly the reason manger takes its extra e: the ending begins with o.

FrenchEnglishListen
je commenceI start
tu commencesyou start
il / elle commencehe / she starts
nous commençonswe start
vous commencezyou start
ils / elles commencentthey start
The rule

C is soft (an s sound) before e, i and y, and hard (a k) before a, o and u. When an ending forces a hard context onto a stem that needs to stay soft, French writes ç. The cedilla only ever appears before a, o or u — you will never see çe or çi, because they would be pointless.

Every -cer verb does it

Avancer (to move forward), placer, lancer (to throw), remplacer, prononcer. And you already know the pattern from a noun: français.

Commencer à or commencer par?

Both are common and they say different things — the same split finir makes with de and par.

FrenchMeans
je commence à travailler I’m starting to workbeginning the activity
je commence par le dessertI’ll start with dessertfirst of several
le film commence à huit heuresthe film starts at eightà for a time too
ça commence bienthat’s a great startusually sarcastic
Commencer par means “start with”

It names the first item in a sequence, not the activity itself. Commençons par le début — “let’s start at the beginning”. Its opposite is finir par, “to end up”.

Passé composé — commencé

No cedilla — the ending is -é, so the c is already soft. J’ai commencé.

FrenchEnglishListen
j’ai commencéI started / have started
tu as commencéyou started / have started
il / elle a commencéhe / she started / have started
nous avons commencéwe started / have started
vous avez commencéyou started / have started
ils / elles ont commencéthey started / have started

Imparfait — the cedilla returns

Four of the six imparfait endings begin with a, so the hook is back: je commençais. Nous commencions and vous commenciez take i endings and drop it.

FrenchEnglishListen
je commençaisI used to start / was starting
tu commençaisyou used to start / was starting
il / elle commençaithe / she used to start / was starting
nous commencionswe used to start / was starting
vous commenciezyou used to start / was starting
ils / elles commençaientthey used to start / was starting

Futur and conditionnel — no hook

Built on the full infinitive, where the c is followed by e: je commencerai. Nothing needed.

FrenchEnglishListen
je commenceraiI will start
tu commencerasyou will start
il / elle commencerahe / she will start
nous commenceronswe will start
vous commencerezyou will start
ils / elles commencerontthey will start

Conditionnel — would start

Je commencerais par… is a natural way to offer a suggestion: “I’d start with…”.

FrenchEnglishListen
je commenceraisI would start
tu commenceraisyou would start
il / elle commenceraithe / she would start
nous commencerionswe would start
vous commenceriezyou would start
ils / elles commenceraientthey would start

Subjonctif — regular

Every ending begins with e or i, so there is no cedilla anywhere in this tense.

FrenchEnglishListen
je commence(that) I start
tu commences(that) you start
il / elle commence(that) he / she start
nous commencions(that) we start
vous commenciez(that) you start
ils / elles commencent(that) they start

Impératif — commençons

Commence ! with no s, and commençons ! keeping its hook — “let’s begin”, and one of the few places you will actually write a cedilla by hand.

FrenchEnglishListen
commence !start! (to one person you know)
commençons !let’s start!
commencez !start! (formal, or to a group)

Plus-que-parfait — had started

J’avais commencé.

FrenchEnglishListen
j’avais commencéI had started
tu avais commencéyou had started
il / elle avait commencéhe / she had started
nous avions commencéwe had started
vous aviez commencéyou had started
ils / elles avaient commencéthey had started
