Ser and estar about a person: what kind of person and how they are now

Describing a person, you have to pick between ser and estar, and the pick changes the meaning rather than the shade. For example: “Mi hermano es muy tranquilo, pero hoy está nerviosísimo” — My brother is very calm, but today he is terribly nervous. A rule from the Spanish course: worked out on examples, not memorized as a wording.

How it works

Describing a person, you have to pick between ser and estar, and the pick changes the meaning rather than the shade.

Ser answers 'what kind of person is this': looks, character, origin, job. Es alto, es generoso, es profesor. Estar answers 'how is he right now': mood, health, place. Está nervioso, está cansado.

With some adjectives the switch gives a different English word. Es aburrido is 'he is a boring man'; está aburrido is 'he is bored'. Es listo is clever; está listo is ready.

Looks go either way. Es delgada is thin always; está más delgada means she has slimmed. Hence ¡qué guapa estás! is 'you look lovely today', while eres guapa is about the person.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
