IPA: /ˈθrɛnədi/
KK: /ˈθrɛnəˌdi/
A type of song or poem that expresses sorrow, especially for someone who has died.
The choir sang a beautiful threnode at the memorial service.
Threnode is derived from the Greek "threnos" (meaning lament or dirge) and the suffix "-ode" (meaning song or ode). The word refers to a song of lamentation, typically expressing sorrow or mourning.
Think of a 'lament' ('threnos') being expressed in a 'song' ('-ode') — that's why a threnode is a song of mourning.
