Overview

Estar is a fundamental Spanish verb used primarily to express temporary states or conditions and locations. Unlike ser, which relates to inherent characteristics or identity, estar focuses on how someone or something is at a specific moment or where they are located. It is an irregular verb, so its conjugation does not follow the standard patterns.

Usage of Estar

This verb is used to describe temporary physical or emotional states, ongoing actions (as part of present progressive), and physical locations of people, places, or things. For example, you say "Estoy cansado" (I am tired) to express a temporary feeling, or "El libro está en la mesa" (The book is on the table) to indicate location.
