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
Figuratively, kaiuttava can sometimes be used to describe a person who talks at length, implying a propensity
Etymology notes: the form is built from kaiuttaa or kaiku-related roots with the participial suffix -ttava,
