How do you say sentences in spanish?

The Wording of the question is confusing.

If you want to have a sample sentence in Spanish: "Hola amigo, soy Emma." is a perfect example.

If you want to know the Spanish Word for sentence it is either "oración" or "frase" depending on the country in question. "Oración" can also mean "prayer" and "frase" can also mean "phrase" in certain countries.
