Castilian lessons Parte 1

Hello my dear friends. I'm on this blog for teaching you and I want say you some words in Castilian or Spanish, and I think that it will better say you: 
¿Cómo están? I know it means How are you? (only for you in its plural meaning, for you in singular is ¿Cómo está?). And we could answer ¡Muy bien! = We're fine.(but it isn't the exact translation guys, the  translation is very good literally).
In Spanish there are two forms for talking with the people, tú (you) and usted (it's you too).
Ustedes is you in plural sense.
(the Castilian orthography is very simple, so the only difficulties when write Spanish are the rules for writing B or V that   soin Castilian sound the same, the rules for write C or Z in certain words, the rule for write the H letter and the rules for write LL instead the Y , HI instead Y, W instead HU, K instead C or QU, QU instead C, or M instead N, and R instead RR.
It isn't complicated, ok?.
In Hispanic America C (only before E and I), S and Z are the same. For example cerebro (brain) it pronounces se'rebro. Zorrillo (skunk) it pronounced so'rio. Ciruela sounds si'rwela. Zamaquear sounds sama'kear, etc.
Don't worry people, I'm going teaching you all about Spanish, especially about the Latin Spanish. I will include many conjugations and words that don't exist in the dictionary of the Royal Spanish Academy
