Tip. Drop Subject Pronouns
Because the endings of Spanish verbs indicate who the subject of an action is, you can often drop the subject pronoun (yo, tú, nosotros, etc.)
e.g.
Yo hablo Español = I speak Spanish ” Hablo Español ”
The pronoun “yo” isn’t really necessary. The “-o “ ending tells you who the subject of the verb is.
