What Is Ser and Why Does It Matter?
Spanish has two verbs that both mean "to be" in English: ser and estar. Ser is used for characteristics that are considered permanent, defining, or inherent to identity. Choosing the wrong one changes the meaning of a sentence entirely — Él es aburrido (He is a boring person) vs. Él está aburrido (He is bored right now). This guide covers every situation where ser is correct.
