Relating to or written in the style of an elegy; expressing sorrow, lamentation, or melancholy in a formal or literary way.
From elegy (Greek elegeia, from elegoi meaning 'songs of mourning') plus the suffix -iacal (from -iac + -al). Elegiac is the standard form, while elegiacal is a less common variant with an extra suffix layer.
The Greeks invented elegies—mournful poems in a specific meter—and the word stuck around so long that we keep adding suffixes to it, creating variants like elegiacal that sound extra dramatic and scholarly.
