Tu peux corriger cette faute toi-même.

Tu is the singular, informal word for you. It is used when speaking to:

• one friend
• a child
• a family member
• someone you know well

Vous is used for:

• one person in a formal situation
• more than one person

So this sentence is addressed to one person informally. A formal version would be:

Vous pouvez corriger cette faute vous-même.

Peux is the tu form of the verb pouvoir, which usually means can or to be able to.

So:

• tu peux = you can
• je peux = I can
• il peut = he can

In this sentence, tu peux means you can or you’re able to.

Because after pouvoir, French uses an infinitive.

So the pattern is:

• tu peux corriger = you can correct
• je peux venir = I can come
• nous pouvons aider = we can help

In English, we also do something similar: after can, we use the base form of the verb:

• you can correct not
• you can corrects

So corriger stays in the infinitive.

Corriger means to correct. It is a regular -er verb, although its spelling changes in some forms to keep the soft g sound.

For example:

• nous corrigeons
• je corrigeais

But in the infinitive, it is simply corriger.

In this sentence, it means to correct/fix a mistake.

Cette means this and agrees with a feminine singular noun.

The noun here is faute, and faute is feminine singular, so you need:

• cette faute = this mistake

Compare:

• ce livre = this book
• cet exercice = this exercise
• cette faute = this mistake
• ces livres = these books

Faute means mistake, error, or sometimes fault.

It is similar to erreur, but there can be a slight difference in usage:

• erreur is a general error/mistake
• faute can sound like a mistake, especially in writing, grammar, spelling, or something considered “wrong”

So in a sentence like this, cette faute often suggests this mistake/error, possibly in writing or language.

Examples:

• une faute d’orthographe = a spelling mistake
• une faute de grammaire = a grammar mistake

Toi-même means yourself.

It is the stressed pronoun toi plus même, which adds the idea of self or personally.

So:

• toi-même = yourself
• moi-même = myself
• lui-même = himself
• elle-même = herself
• nous-mêmes = ourselves
• vous-même / vous-mêmes = yourself / yourselves
• eux-mêmes / elles-mêmes = themselves

In this sentence, toi-même emphasizes that you can do it personally, without someone else doing it for you.

French normally writes these emphatic pronoun forms with a hyphen:

• moi-même
• toi-même
• lui-même
• elle-même
• nous-mêmes
• vous-même
• eux-mêmes

So the hyphen is just the standard spelling.

Also notice that même may take an -s in plural forms:

• nous-mêmes
• vous-mêmes
• eux-mêmes
• elles-mêmes

At the end, toi-même gives emphasis, a bit like:

• You can correct this mistake yourself.

The idea is that you do not need someone else to do it.

French often puts this kind of emphatic element after the main part of the sentence:

• Je l’ai fait moi-même. = I did it myself.
• Elle peut venir elle-même. = She can come herself.

So ending with toi-même sounds natural and highlights yourself.

Yes, but it is not exactly the same in every context.

• toi-même usually means yourself, with emphasis on you personally
• par toi-même often means by yourself or on your own

So:

• Tu peux corriger cette faute toi-même.
  = You can correct this mistake yourself.

• Tu peux corriger cette faute par toi-même.
  = You can correct this mistake by yourself / on your own.

The second version stresses without help a little more clearly.

Grammatically, it is a statement, not an imperative.

• Tu peux corriger cette faute toi-même. = You can correct this mistake yourself.

But depending on tone and context, it can function like a suggestion or a gentle instruction.

A real command would be:

• Corrige cette faute toi-même. = Correct this mistake yourself.

So tu peux... sounds softer than a direct order.

If you are speaking formally to one person, or to more than one person, you use vous:

• Vous pouvez corriger cette faute vous-même.

If speaking to several people, you could also have:

• vous-mêmes when the meaning is clearly plural in an emphatic sense

Examples:

• singular formal: Vous pouvez corriger cette faute vous-même.
• plural: Vous pouvez corriger cette faute vous-mêmes.

In everyday writing, context usually makes it clear whether vous is singular or plural.

A simple pronunciation guide is:

Tu peux corriger cette faute toi-même.
≈ ty puh ko-ree-zhay set foht twa-mem

A few useful notes:

• tu sounds like ty with a French u
• peux sounds roughly like puh
• corriger ends with -zhay
• cette sounds like set
• faute sounds roughly like foht
• toi-même sounds like twa-mem

The final -e in faute and même is not pronounced as a separate syllable.
