Ser vs estar · Spanish 1000

Why two verbs?

English has one “to be”. Spanish splits it into ser (more permanent / identity / classification) and estar (location / temporary state / result). Choosing wrong sounds unnatural: Soy aburrido = I am a boring person; Estoy aburrido = I am bored right now.

Both verbs are highly irregular in the present — learn them together from the start.
