ingeniare and ingenium in Latin Alphabet

[cj8990]

Forgive me if this question shows my ignorance but how would these latin words have been spelled in antiquity considering, for example, there is no U in the classical latin alphabet?

Ingeniare and Ingenium

Thank you!

ingeniare doesn't seem to be a classical Latin word, so it wouldn't have been spelled in antiquity at all.

Ingenium would be spelled INGENIVM (v and u were the same letter).
There's also Roman cursive, though (look at the "cursiva antigua" parts)
