I got confused about about "nosotros" and "nosotras". I didnt realize that in spanish languge the spelling was dependent on gender. Like in other languages (eg French, English..ie "Nous" /"we") would apply across the board regardless of gender. Was confusing at first but it makes sense. Not sure if I was the only one who got mixed up with this.
They are all conjugated forms of the verb "leer" yo: leo tú: lees él/ella/Ud.: lee nosotros: leemos vosotros: leéis ellos/ellas/Uds.: leen
You use yo when your talking about yourself Tú when your talking about "you" él or ella when you are talking about "he" or "she" nosotros - we vosotros - they (vosotros is only used in Spain) ellos or ellas - they Now Ud. and Uds. are just formal versions of the word "you" however you still need to conjugate the word just like "él/ella" has or "ellos/ellas."
When conjugating a word, you take out the ending, AR, ER, IR; then you replace it with the following ending (depending on who you are talking about) For AR Verbs (ends with ar, ex. hablar): YO - o TÚ - as ÉL/ELLA/UD. - a NOSOTROS - amos VOSOTROS - áis ELLOS/ELLAS/UDS. - an
For ER Verbs (ends with er, ex. comer): YO - o TÚ - es ÉL/ELLA/UD. - e NOSOTROS - emos VOSOTROS - éis ELLOS/ELLAS/UDS. - en
For IR Verbs (ends with ir, ex. vivir): YO - o TÚ - es ÉL/ELLA/UD. - e NOSOTROS - imos VOSOTROS - ís ELLOS/ELLAS/UDS. - en
It is also important to remember that Spanish has masculine and feminine words. You asked about "lea" and "lee" Well, "lea" would be used when you are talking about HER. You don't use "lea" when you're talking about a guy. "Lee" would be used when you are talking about HIM. However, there is an exception to this rule. For instance, you may be talking about THEM (ellos); ellos can either be talking about males ONLY, or BOTH males and females. You may say, ellos beben leche. In that case, I could be talking about guys, or both guys and girls.
Hopefully this cleared things up a little :)
