Meeting someone for the first time

Encantado/a

en-kan-TAH-doh — Pleased to meet you

"— Esta es Ana. — Encantado, soy Carlos."
— This is Ana. — Pleased to meet you, I'm Carlos.

Adjust the ending to your own gender (encantado if you're male, encantada if female) regardless of who you're meeting — a common small mistake is matching the other person's gender instead of your own.
