From inter- (“between, among”) + eō (“go”).
intereō (present infinitive interīre, perfect active interiī, supine interitum); irregular conjugation
- I go among, become lost in.
- I am ruined, undone.
Irregular conjugation, but similar to fourth conjugation. The third principal part is most often contracted to interiī, but occasionally appears as interīvī.
