In this video, we learn how to make Informal and formal commands in Spanish. When you speak in first person singular, you will say "yo" when you speak in plural, you will say "nosotros". These are both informal or familiar forms of the word. When you are speaking to someone that is a elder, you will want to speak in formal instead of informal. Use informal mode when you are talking with friends, family, children, and anyone else you talk to in a daily basis. Pay attention if you are talking about groups of people, pay attention to how you are talking to them so you say the right command without coming off rude or too casual.
