"I read a lot."
Translation:Yo leo mucho.
Yo leo, Tù lees, él/ella/usted lee. Leer is the unconjugated form so only used with other verbs (ex. Yo tengo leer).
-er/ar verbs (beber, comer, leer, pagar are some main onea DL had taught in beginning lessons).
From what i can tell, it is like the bebo, bebes, bebe thing. Differert verbs for different pronouns. Leo is for yo (just like bebo is for yo). So the one that ends in o is the one you use with yo.
