From con- + eō (“go”).
coeō (present infinitive coīre, perfect active coiī or coīvī, supine coitum); irregular conjugation
- to assemble, meet, come together
- in triclinio coeam, in cubiculo nolam ― I meet (you) at the table but I won’t at the dormitory
- to encounter, come up against
- to copulate, have sex
- to join, ally with
- to unite, come together as a whole
- to mass together, ball up, curdle
- The only noun that is ever attested as an object of coeō is societatem (as societatem coire, "to [come together to] form an alliance") in Gaius's Institutes. The use of the accusative is classified as a cognate accusative.
Irregular conjugation, but similar to fourth conjugation. The second principal part is most often contracted to coïī, but occasionally appears as coīvī.
