Introduction

Gender
In Spanish, all nouns are either masculine or feminine. Often, nouns end in ‑o if they're masculine and ‑a if they're feminine.
el niño
the boy
la niña
the girl
Notice how you use el if the word is masculine and la if the word is feminine.
The apple is a girl?!
It's not just people that are masculine or feminine in Spanish. Objects are, too!
el pan
the bread
la manzana
the apple
Not sure what gender something is? Look at the the! If a word uses el, it's masculine. If it uses la, it's feminine.
I think, therefore…
In English, verb forms change depending on who's doing the action. For example, we say I am, you are, and she is. In Spanish, you do the same thing.
