Elegy & Eulogy

Elegy and eulogy are both related to the dead, but in different ways.
Elegy is chiefly, a poem of sorrow for the dead: “Thomas Gray wrote a famous elegy which is often quoted at funerals.”
Eulogy, on the other hand, is high praise, written or spoken, usually about someone who has died: “Surrounded by her friends and family , Taylor Armstrong bravely delivered a eulogy for her husband Russell Armstrong — still wearing her wedding ring..”
