obituary

PIE word *h₁epi Learned borrowing from Medieval Latin obituārius (“obituary”) + English -ary (suffix denoting something relating to another thing or used in a place). Obituārius is derived from Latin obitus (“act of approaching or going toward, an approach; act of going down, setting; of the sun: sunset; death; destruction, downfall, ruin”) + -ārius (suffix forming adjectives and agent nouns); while obitus is a noun use of the perfect passive participle of obeō (“to go to meet, go towards; (figurative) to die, pass away, perish; (astronomy) to set”), from ob- (prefix meaning ‘toward’) + eō (“to go, move”), ultimately from Proto-Indo-European *h₁ey- (“to go”).
