What a person is like: character suffixes and ser against estar

The unit about character stands on adjectives, and almost all of them are assembled from a noun plus a suffix. Knowing four rows, you understand a word you have never seen. For example: “Es un chico tímido, pero hoy está muy hablador” — He is a shy guy, but today he is very chatty. A rule from the Spanish course: worked out on examples, not memorized as a wording.

How it works

The unit about character stands on adjectives, and almost all of them are assembled from a noun plus a suffix. Knowing four rows, you understand a word you have never seen.

-oso — 'full of': el orgullo → orgulloso, la envidia → envidioso, el cariño → cariñoso, la pereza → perezoso, el peligro → peligroso. The most productive row — English has the same suffix in '-ous': 'famous', 'nervous'.

-ivo — inclined to do: la actividad → activo, la agresión → agresivo, la impulsión → impulsivo. -able and -ible — the same as English '-able': amable, agradable, insoportable — unbearable. -ón — with a boost and almost always a smirk: la cabeza → cabezón (big-headed), llorar → llorón (a crybaby), dormir → dormilón (a sleepyhead).

The reverse move works too: from an adjective a noun is made in -dad, -eza or -ía: bueno → la bondad, perezoso → la pereza, cabezón → la cabezonería, honrado → la honradez.

Now the main thing — ser or estar with a character trait. Ser names a property of the person: Es tímido, Es muy directo, Es una persona reservada. Estar names a state right now: Está callado hoy — quiet today, Está insoportable — unbearable today. English splits it the same way: 'he is shy' against 'he is being quiet tonight'.

For part of the words the two verbs give different meanings, and the difference stings: ser listo — clever, estar listo — ready; ser aburrido — a bore, estar aburrido — bored; ser bueno — good, estar bueno — tasty (about a person, a backhanded compliment); ser orgulloso — vain, estar orgulloso de — proud of something.

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.
