ser and estar — two verbs 'to be'

English gets one 'to be' for everything; Spanish insists on two, and the choice between them is the first habit to build. For example: “Soy ruso” — I'm Spanish (that's what I am, always). A rule from the Spanish course: worked out on examples, not memorized as a wording.

How it works

English gets one 'to be' for everything; Spanish insists on two, and the choice between them is the first habit to build.

ser — what something IS, its essence: profession, origin, character, what a thing is made of. estar — how something IS right now: state, mood, feelings — and also location.

The classic pair: Es aburrido — he is a boring person; Está aburrido — he is bored right now. Same adjective, different verb, different sentence.

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.
