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

English hears the difference in 'he is funny' against 'he is being funny'; Spanish has to make the same choice with the verb itself, and with people it changes the meaning, not 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

English hears the difference in 'he is funny' against 'he is being funny'; Spanish has to make the same choice with the verb itself, and with people it changes the meaning, not the shade.

Ser answers 'what kind of person is this': looks, character, origin, profession. Es alto, es generoso, es de Sevilla, es profesor. Estar answers 'how is he right now': mood, condition, situation. Está nervioso, está cansado, está en casa.

There are adjectives whose translation changes with the choice, and they must be known on sight. Es aburrido — he is a boring person; está aburrido — he is bored right now. Es listo — he is clever; está listo — he is ready. Es bueno — he is kind; está bueno — it is tasty (about a person it is a compliment on looks, and not one to deliver face to face). Es despistado — scatterbrained by nature; está despistado — not himself today.

Looks can go either way: es delgada — she is thin, that is her build; está más delgada — she has slimmed down, she has changed. So ¡qué guapa estás! is 'how great you look today', a compliment to today's appearance, while eres guapa is a statement about the person in general.

Age and height go through tener and medir, not through 'to be': tiene treinta años, mide uno setenta. And a third verb, parecer, lifts the responsibility off the speaker: parece simpático — he seems nice, but I would not vouch for it.

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.
