kaiuttava

Kaiuttava is a Finnish adjective and present participle formed from the verb kaiuttaa (to cause to echo) or from the related concept of kaiku (echo). The primary sense of the word is related to sound: it describes something that produces, echoes, or carries noise, often in a way that is audible or resonant. The suffix -ttava marks a property or ongoing action, so kaiuttava explains a characteristic rather than a one-time event.

In usage, kaiuttava appears mainly in descriptive, literary, or technical contexts. It is not the standard everyday term for a loudspeaker; that device is usually referred to by the noun kaiutin. Nevertheless, kaiuttava can describe a system, material, or environment that emits or propagates sound, for example kaiuttava järjestelmä (a sound-producing system) or kaiuttava kaiku (an audible echo). In acoustic descriptions, the term may convey that a surface or space enhances or transmits sound in some way.

Figuratively, kaiuttava can sometimes be used to describe a person who talks at length, implying a propensity to “echo” conversations or to produce a lot of spoken output. Such usage is relatively rare and more common expressions or forms are typical in everyday language.

Etymology notes: the form is built from kaiuttaa or kaiku-related roots with the participial suffix -ttava, aligning with other Finnish adjectives that denote a characteristic action.
