Jätkvelkäiku
Jätkvelkäiku is a term of Finnish origin, generally referring to a prolonged echo or reverberation of a sound. The word is a compound, formed from "jätkä," meaning a lumberjack or woodsman, and "velkäiku," which describes a fading or lingering echo. Historically, the term was likely used to describe the way sounds would carry and echo in the vast, sparsely populated forests of Finland, particularly those associated with logging activities.
