näyttäytyvät

Näyttäytyvät is the present tense, third-person plural form of the Finnish verb näytäntyä (to appear, to manifest oneself; to behave, in reflexive sense). The form is used when referring to multiple subjects that are demonstrating a behavior or that are becoming evident in a given situation.

Two primary senses exist for näytäntyä:

- to appear or become evident, as in phenomena, symptoms, or situations (ilmiöt tai oireet näyttäytyvät);

- to behave or conduct oneself, particularly in social contexts, though this sense is more commonly expressed with the more common verb käyttäytyä.

In everyday Finnish, the nuance is often determined by context. When speaking about how something or someone presents itself or becomes noticeable, näytäntyä is used. When referring to general conduct or manners, käyttärtyminen (via käyttäytyä) is typically used, though näytäntyä can appear in more formal or literary contexts to emphasize manifestation.

Etymology: näytäntyä is a compound formed from the root näytä- (to show, to appear) with a reflexive/-ty- suffix that yields the intransitive sense of “to present oneself” or “to become apparent.” The noun form näytäytyminen is related and can denote manifestation or appearance.

Related forms include näytätyksiä (variants in noun forms) and other person forms of näytäntyä, as well as synonyms such as ilmestyä (to appear) in contexts emphasizing emergence, or käyttäytyä (to behave) in social behavior contexts.

Examples:

- Oireet näyttäytyvät varhaisessa vaiheessa. (The symptoms appear in an early stage.)

- Ilmiö näyttäytyy moninaisena tutkimuksen edetessä. (The phenomenon manifests in many forms as the study progresses.)

Overall, näytätyvät functions as a versatile form indicating appearance or manifestation in multiple subjects, with context guiding whether it leans toward behavior or perception.
