Forms
immorior (present infinitive immorī, perfect active immortuus sum); third (-iō variant) conjugation, deponent[1] It is also spelled inmorior.[2][3]
Etymology
It is from Latin in- + morior (“to die”).[2][4][1] The simple verb goes back to Proto-Italic *morje- and Proto-Indo-European *mr̥-ie/o- (“to die”).[5]
Earliest recorded meaning
The TLL records it from the Culex and Horace on.[4] Horace uses it hyperbolically of a man who “dies over” his pursuits and grows old in the love of gain (immoritur studiīs).[2]
Semantic evolution
It is a word of poetry and of post-Augustan prose.[6] It means to die in or upon something, usually with the dative: in Ovid one sister dies upon another, and Pliny the Elder writes of honey in which bees have died.[2][6] It also means to die in the middle of an activity or a suffering: Seneca has a man who dies while going through his accounts, and Quintilian someone who says he will die on his embassy.[2]
Ecclesiastical and medieval Latin kept the sense “to die”;[7][3] Florus of Lyon uses it of the grain that dies in the earth, after the Gospel of John, and the perfect participle could be a noun, “the dead woman”.[7][3]
