A threnody is a song or hymn of mourning composed or performed as a memorial to a dead person. The term originates from the Greek word threnoidia, from threnos (a "lament") + oide ("song"); ultimately, from the Proto-Indo-European root wed- ("to speak") that is also the precursor of such words as "ode", "tragedy", "comedy", "parody", "melody" and "rhapsody". Synonyms include "dirge", "coronach", "lament" and "elegy".
