Ser vs estar

Spanish has two verbs meaning "to be": ser and estar. Choosing the right one is essential for clear communication. While the distinction can seem tricky at first, clear patterns govern their use.

The key distinction

The fundamental difference:

• ESTAR = How something IS (state, condition)

Think of it this way:

• Ser answers: "What kind of thing/person is this?"
• Estar answers: "What's the current situation?"

Same adjective, different meaning

Many adjectives change meaning depending on which verb you use:

SER + adjective	ESTAR + adjective
Es aburrido. (He's boring.)	Está aburrido. (He's bored.)
Es listo. (He's clever.)	Está listo. (He's ready.)
Es malo. (He's bad/evil.)	Está malo. (He's sick.)
Es bueno. (He's good/kind.)	Está bueno. (It tastes good / He looks good.)

Location: A special case

Physical location uses ESTAR:

• La escuela está en la calle Mayor. — The school is on Main Street.
• ¿Dónde está tu casa? — Where is your house?

Events use SER (for when/where they happen):

• La boda es en la iglesia. — The wedding is at the church.
• La reunión es a las tres. — The meeting is at three.

The logic: Events aren't "located" somewhere; they "take place" there.
