Es vs eres
I can't seem to get when to use each one - help! Does it depend on male or female or first person versus third person?
Es is third person singular (he, she, it, you formal) for the verb Ser which means to be.
Eres is the second person singular (you) for the same verb.
So it goes: Yo soy (I am), Tú eres (you are), él es (he is), ella es (she is), ellos son (they are) etc.
Look at the conjugation of the verb Ser, here. http://www.spanishdict.com/conjugate/ser
Does that make sense to you?
In English we say "I am, you are, he is, she is, they are" etc. The way a verb changes depending on who it is doing the action is called the conjugation of the verb. That link I gave you will help you find the conjugation for any verb you know in Spanish.
Let me know if that clears up your confusion. Please ask if you still are unsure. Good luck!
You are right Tatiana!
I am = Yo soy You are = Tu eres He/She is = Él/Ella es They are = Ellos son We are = Nosotros somos You are = Vosotros sois
In spanish this terminations are differents than english, but with practice you will do right! Come on!
PS= If I have some mistake in my english writting, you can correct me. Thanks you!
