English

ser and estar — two verbs 'to be'

Spanish keeps two verbs where English has one 'to be', and you choose between them in almost every sentence. For example: “Soy ruso” — I'm Russian (that's what I am, always). A rule from the Spanish course: worked out on examples, not memorized as a wording.

How it works

Spanish keeps two verbs where English has one 'to be', and you choose between them in almost every sentence.

ser — what a person or thing is: job, origin, character, material. estar — how it is right now: mood, health, and where it stands.

The same adjective changes meaning with the switch. Es aburrido says he is a boring man. Está aburrido says he is bored today. A place never takes ser: la llave está en la mesa.

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.
