ärtyy

ärtyy is a Finnish verb meaning "gets angry" or "becomes irritated." It is the third-person singular present tense form of the intransitive verb ärtyä and is used to describe someone who is growing angry or annoyed. The word conveys a sense of rising irritation rather than a sudden outburst.

In usage, ärtyy is used with a subject in the nominative and does not take a direct object. Common constructions include statements such as "Hän ärtyy helposti" (He/she gets angry easily) or "Kun asiat eivät mene niin kuin pitää, hän ärtyy" (When things don’t go as they should, he/she becomes irritated). The form is often contrasted with suuttua, which more strongly emphasizes a quick or intense outburst of anger. The related participles and adjectives include ärtynyt (angry, irritated) and ärtyminen (irritation, irritability).

Etymology and related forms: ärtyy comes from the Finnish verb ärtyä, a native Finnic verb meaning to become irritated or annoyed. The noun ärtyminen refers to the state of irritability or anger, while ärtynyt is the past participle used as an adjective. The root baring the emotional sense is common in Finnish expressions describing mood and temperament.

See also: suuttua, which emphasizes a stronger or more sudden anger, and ärsyttää, which means to irritate (someone) or to be irritating. Related terms include ärtyneenä (in an irritated state) and ärtyneeksi (into an irritated state, used in certain constructions).
