Difference between Tu and Vous?
A good way to think of Vous when it is plural is "you all", or in the US the colloquial "y'all" from the Southern US.
In languages derived from romantic roots, there are 6 pronouns, 3 for singular: I, you, he/she and 3 for plural: we, you, they. They are refered as "first person singular" in the case of I, "first person plural" in the case of we. As you can see, "first person" includes yourself.
Second person in some anglo-rooted languages are the same for singular and plural, but in french, spanish, italian, czech and so on, there's a difference between "you" (second person singular, Tu in french) and "you" (second person plural, vous in french".
This rule also applies for third person singular ,he/she and third person plural ,they.
As evan10s said, Tu is singular and informal. Vous is formal singular or plural.
If it helps, you could try reading the Wikipedia article on "Thou". English went through a similar phase after "You" had stopped being plural-only but before we'd completely gotten rid of thou/thee/thy/thine.
Tu is you (singular) And Vous in you (plural). Kind of like "y'all" Also, you can use vous in a formal tense.
Vous is used commonly in France when you don't really know the person. However, if you are in Quebec, vous is quite formal and isn't used often (except when you're referring to the plural, "you").
"Tu" is second person singular amongst people you know well. "Vous" is for either second person plural and second person formal which you would use with people or a person you do not know well or with whom you are showing respect, as opposed to "tu". Examples for second person formal would be your teacher, boss, etc.
Tu is used when talking to one person, vous is used when talking to two or more.
Tu - singular and informal. Vous - formal singular or plural
Tu as faim. = You are hungry. (informal; one person) Vous avez faim. = You / you all are hungry. (formal; one or more people)
@Arjofocolovi - I know, my mistake. Thanks for pointing that out!
They both are you. Tu is the singular form. Vous is the plural form or the form used to show respect. -er verbs are conjugated with -es for tu and -ez for vous.
not completely true ex: in the verb "faire" the conjigation for vous isn't -ez it is fete, not a good way of thinking about it
You use "tu" when speaking with one person with whom you are familiar (think of someone you are on a first name basis with for "tu"). You use "vous" for multiple people or in formal settings such as when speaking to your boss.
"tu" is mostly used informally. For example, an adult addressing a child. On the other hand "vous" is used for formal speaking. (a child talking to an adult) or a group of people (plural).
Tu: (You) When talking to friends and family that you know well. It's informal. You's use it with people you know well, even a baby.
Vous: (You) When talking to a stranger, or even a C.E.O. of a company. It's formal. You'd use it when talking to people you don't know well or you want to be respectful to.
If talking to a group of people, use vous. Also use vous when talking to one stranger.
tu is an more informal singular form like "tum" in hindi and Urdu whereas "vous" is a more formal singular form of you like "aap" (Hindi-Urdu reference to make it easirer for ApoorvaJ whose screen name seems like he belongs to the Indian subcontinent. ) "vous" is also the ONLY plural form of the word you in French as rightly pointed out by csi
tu is informal (for your friends, pets, animals) and vous is formal(for your teachers, parents)
Tu means you and is connected to es which means are so its tu es which is you are. You would use it to address some one younger than you or someone that you are close friends with. Vous is the same thing but it is connected to etes so its vous etes. You use ut to address some one older than you or some one you respect. For example if you are addressing your boss you would use vous etes because you are being formal. Hope this helps! ;)
Tu in French means 'you' in an informal way, like in the way you might address a friend or someone you've known for a long time. Vous in French means 'you' as well, but in a more formal way, like in the way you might address someone you've never met before, or your boss.
