1. To be

 

I am going to start the lessons with to be: 

In English you conjugate the person as 1st person singular etc, in the way you see below. On the right you see the translation of it.

I                                               Yo   
                 
You                                         Tú

He                                            El

She                                          Ella 

It                                               Es

We                                           Nosotros

You                                          Vosotros       Here we are talking about you in the plural form.

They                                        Ellos/Ellas     Ellos is used when refering to a group of males or a mixed group.
                                                                         Ellas is used when reffering to a group of females. 

You have to know this when you are learning how to conjugate the verb "TO BE"
I am going to write down how you conjugate it in English at the left, and then Spanish under.

English: 
[ I AM ]             I am Paola                                                            

[ YOU ARE ]     You are Paola                                                    

[ HE IS]           He is Pablo                                                           

[ SHE IS]        She is Paola                                                       

[ IT IS]             It is Paola                                                           

[ WE ARE]       We are Paola and Pablo                              

[ YOU ARE]      You are Paola and Pablo                       

[ THEY ARE]      They are Paola and Pablo 

Spanish:                       
In spanish you don't have to write yo, tu, ++ in front of your sentence like you have to in English. So if you want to say "I am Paola", you just say " soy Paola. Because you know that is just (yo) that's using "soy". But if you really want to, or think it's easier you can have the person in front. " Yo soy Paola".

[ YO SOY]                         ( Yo) Soy Paola
[ TÚ ERES]                        ( Tú ) eres Paola)
[ EL ES]                              ( El ) es Pablo)
[ ELLA ES]                         ( Ella) es Paola)
[ ES]                                    ( Es)  Paola)
[NOSOTROS SOMOS]    ( Nosotros) somos Paola y Pablo                    PLURAL
[VOSOTROS SOIS]          ( Vosotros) sois Paola y Pablo                         PLURAL
[ELLOS/ELLAS SON]       ( Ellos) son Paola y Pablo                                 PLURAL and a group of mixed genders then we use Ellos instead of Ellas.

Summary:
You don't have to have Yo, tu etc, in front of your sentences. It's enough to write for example : " soy Paola" Since it's SOY, you know that it's I AM.
At the last sentence " Ellos son Paola y Pablo" You have to use ELLOS instead of ELLAS because it's a group of mixed genders. If you want to say " They are Lisa and Paola", you are using "Ellas" because it's a group of females. When you are talking about a group of men you are using "Ellos".
"Y" Is the same as "AND" in English. " Paola and Pablo", Paola y Pablo"

If you did'nt understand send me a letter, and I will try to explain to you
