Phrase One: Ça va? Ça va. (‘How are you? I’m fine.’)
After greeting and saying hello to someone, you will need to ask how she or he is. It’s a matter of politeness.
The Question and Statement With ça and va:
While in France you’ll often hear these two sounds [sa-va], which are part of the phrase Ça va ?, meaning “How are you?”
Be aware though, these two tiny words can be either a question or a statement.
To differentiate between the two, you need to listen to the speaker’s intonation. When the intonation rises, it will be a question: Ça va ? (‘How are you?’) When the intonation is slightly falling or constant, it will be a statement: ça va (‘I’m fine’).
Phrase Two: S’il vous plaît. (‘Please’)
This phrase is a must for anyone who has de la galanterie (‘some courtesy’).
The original meaning of S’il vous plaît was not only to be polite but also to ask whomever you are speaking to whether he or she would be pleased to do a favor for you, such as answering a question or passing the salt at the table.
Formal “please”: S’íl vous plaît
You’ve guessed it: we use s’il vous plaît [see-voo-play] in French in formal situations or with people you are addressing using vous (the formal ‘you’). It simply means “please” in English.
Informal “please”: S’íl te plaît
If you’d like to say “please” with close friends, colleagues, in a relaxed context, or in short with people you talk to by using the informal personal pronoun tu, use s’íl te plaît [seel-tuh-play].
