esiintyö

Esiintyä is a Finnish verb meaning to perform, to appear, to occur or to present oneself. It is commonly used about performing arts (artists, bands) and about the appearance of phenomena or symptoms. The verb is typically intransitive: a band esiintyy, ilmiö esiintyy. From esiintyä are derived nouns such as esiintyjä (performer) and esiintyminen (performance, occurrence).

Semantic range and usage examples: esiintyä lavalla (to perform on stage), esiintyä tilaisuudessa (to appear at an event), oireet esiintyvät (symptoms occur). It can also describe assumed roles or behavior — for example, esiintyä asiantuntijana (to present oneself as an expert).

Grammatical notes: esiintyä belongs to Finnish verbal morphology and follows regular patterns for verbs ending in -yä/-yä, with vowel and consonant alternations in different forms. Common forms include the present third person singular hän esiintyy and the past tense hän esiintyi. The infinitive is esiintyä and the nominal action form is esiintyminen.

Register and collocations: the verb is neutral and widely used in both spoken and written Finnish. It appears in contexts ranging from casual announcements (bändi esiintyy huomenna) to medical descriptions (oireet voivat esiintyä yhdessä), as well as in formal reporting of public appearances or performances.
