väljendus

Väljendus is an Estonian noun meaning expression, manifestation, or form of expression. It is derived from the verb stem väljend- (to express) with the abstract-noun suffix -dus. The term is used across disciplines to refer to how ideas, feelings, or information are conveyed, and it can denote both linguistic and nonlinguistic manner of communication.

In linguistics, väljendus denotes the manner in which language conveys meaning—style, tone, phrasing, and delivery. Expressions such as väljendusviis (manner of expression) and keeleline väljendus describe not only words but accompanying prosody, gesture, and intonation that shape perception of the message.

In mathematics and the sciences, väljendus translates to a mathematical or symbolic expression: a combination of symbols that represents a value or relationship. Examples include the linear expression 3x + 5 or the algebraic expression a^2 − b^2. The term is common in Estonian textbooks and mathematical discourse.

In arts and culture, väljendus refers to artistic expression—the transmission of ideas, emotions, or worldview through media such as painting, sculpture, music, or performance. The concept is often linked with väljendusvahendid (means of expression), the tools and methods an artist uses to communicate meaning.

Related forms include väljende- (expressive) and väljend, a noun meaning “expression” in a narrower sense; the verb väljendada means “to express.”
