In Spain, it is common to use formal greetings and introductions, especially when meeting someone for the first time in a professional or formal setting. When using honorifics and titles, the most polite way to introduce yourself would be to say "Soy " followed by your name, which literally means "I am" in Spanish. For example, if your name is Juan Pérez, you would say "Soy Juan Pérez." This is a formal and respectful way to introduce yourself, especially when meeting someone older or in a position of authority. Alternatively, you can use the phrase "Me llamo " followed by your surname, which means "My name is" in English, but it sounds more natural in Spanish. For instance, if your surname is García, you would say "Me llamo García." However, it is generally considered more formal to use the honorific title "Dono/a " or "Señorita/Senor" followed by your name and surname. For example, if you are a woman, you would say "Soy Señorita García" or "Me llamo Doña García." Using honorifics and titles is an important aspect of Spanish culture and will make you sound more respectful and professional when introducing yourself to Spaniards.
