Good night = Bonne Nox

Hi, here it comes, in Latin they used some different expressions like salve to say hello that literally means = be well, be in good health…etc

Good night = bona nox
Good Morning = bonus dies
Hello = Salve
Sorry = Indulgeo mihi (excuse me)
I love you = Ego amo/diligo te

Bona fortuna = good luck
Santus

Good night
–Bonus nox noctis

Good Morning
–Bonus Oriens

Hello
–abyssus

I love you
–EGO diligo vos

The Romans just had expressions for greeting and separating, so their phrases didn’t actually specify “morning” or “night”.
ave = greetings, hello, good morning
vale = goodbye, goodnight
salvere iubeo = I bid you good day
salve = how are you,
amo te = I love you
me paenitet.. = I am sorry.. (Latin says “it causes me sorrow..”)

Trust me, I’m a Latin scholar:

good night is not something the Romans would say as a parting phrase. The parting phrase is “vale” or “valete” (plural). The way to say good night (as in “It was a good night with good weather”) is bona nox.

good morning is also not something the Romans said as a greeting phrase. They said “salve” or “salvete” (plural). The way to say good morning, however, is difficult, because they didn’t have a noun for morning, only an adjective and an adverb. Cassell recommends rendering it with “tempus matutinum” (morning-time). So, “bonum tempus matutinum,” but that is cumbersome and ponderous.

hello is “salve” or “salvete”

sorry is (contrary to what others have suggested) “ignosce mihi”

I love you is “amo te” or “te amo” (it doesn’t matter what the order is).

Zlevad has them well-covered, including the correct version for ‘sorry’.

Mihi ignosce = Excuse/Pardon me. You didn’t ask for this one, but it’s a good one to add to your list – it just doesn’t mean ‘sorry’.
