Spanish greetings matter just like they do in any country.
¿Cómo estás? ¿Cómo está? - How are you? It is a safe way to greet someone, but choose ¿Cómo estás? only if you know the person well or if the person is younger.
Hola, aló - If you are uncertain as to which form of the verb estar, just go for the Spanish version of "Hello".
¿Cómo su va? - an informal way to ask, how it is going.
¿Cómo va? - a shorter version.
Comment ça va? - the French version of ¿Cómo su va? pronounced much the same as the Spanish, except for the su and ça (sue and sah) .
¿Qué pasó? - slangier way to say, what's happening or what happened.
