Les Erreurs Frequentes avec CAN

Les 10 erreurs les plus courantes et comment les eviter

Erreur n°1 : Ajouter "to" apres CAN

C'est l'erreur la plus repandue chez les francophones. En francais, on dit "je peux faire", ce qui incite a traduire "I can to do".

I can to swim.

She can to speak English.

Can you to help me?

I can swim.

She can speak English.

Can you help me?

Erreur n°2 : Conjuguer CAN a la 3e personne

En anglais, les modaux ne se conjuguent jamais. Pas de "-s" a la 3e personne.

She cans drive.

He cans play the guitar.

She can drive.

He can play the guitar.

Erreur n°3 : Utiliser DO/DOES pour les questions et negations

CAN forme ses propres questions et negations, sans auxiliaire.

Do you can swim?

She doesn't can come.

Does he can speak French?

Can you swim?

She can't come. (ou She cannot come.)

Can he speak French?

Erreur n°4 : Ecrire "can not" en deux mots

I can not believe it. (generalement incorrect)

I cannot believe it. (forme pleine, un seul mot)

I can't believe it. (forme contractee)

Exception : "can not" en deux mots est acceptable uniquement quand "not" fait partie d'une autre structure : "You can not only sing but also dance."

Erreur n°5 : Confondre CAN et KNOW HOW TO

I can to cook Italian food. (double erreur)

I can cook Italian food. (capacite)

I know how to cook Italian food. (savoir-faire, equivalent)

CAN vs KNOW HOW TO : Les deux expriment la capacite, mais "I know how to..." insiste sur la connaissance technique. "I can..." est plus general. On peut dire "I can swim" = j'en suis capable, ou "I know how to swim" = j'ai appris la technique.

Erreur n°6 : Utiliser CAN au passe pour un evenement specifique

Yesterday, I could finish the report. (evenement specifique reussi)

Yesterday, I was able to finish the report.

Yesterday, I managed to finish the report.

Rappel : COULD s'utilise pour une capacite generale dans le passe : "When I was young, I could run very fast."

Erreur n°7 : Utiliser CAN au futur

I will can come next week.

She will can help us tomorrow.

I will be able to come next week.

She will be able to help us tomorrow.

On ne combine jamais deux modaux ensemble. "Will" et "can" sont tous les deux des modaux.

Erreur n°8 : Confondre CAN et MAY en contexte formel

Can I have a glass of water? (a un superieur, en reunion formelle)

May I have a glass of water? (formel, poli)

Could I have a glass of water? (poli, courant)

Erreur n°9 : Mal prononcer CAN et CAN'T

Mot	Prononciation correcte	Erreur courante
can (affirmatif)	/kən/ (voyelle reduite, rapide)	Prononcer /kæn/ trop fort
can (accentue)	/kæn/ (reponse courte : "Yes, I CAN")	—
can't (US)	/kænt/ (voyelle claire + T final)	Confondre avec "can"
can't (UK)	/kɑːnt/ (voyelle longue)	Confondre avec "can"

Astuce de comprehension : Pour distinguer "can" de "can't" a l'ecoute, fiez-vous au contexte et a la voyelle. "Can" affirmatif a une voyelle courte et faible (/kən/). "Can't" a une voyelle claire et nette (/kænt/ ou /kɑːnt/).

Erreur n°10 : Oublier les alternatives a CAN

Situation	Au lieu de CAN seul	Alternative
Passe (general)	I can swim when I was 5	I could swim when I was 5.
Passe (specifique)	I could pass the exam	I was able to / managed to pass.
Futur	I will can come	I will be able to come.
