Haughtiness: it means snobby or arrogant. So we might say, “The young man’s haughtiness turned off his prospective bride.”

“Berenice” is Macedonian. It means “bringing victory.”

The closest to “Egaeus” I could find is “Egeus” It is from Greek and means “shield” or “protection.”

Berenice’s name (which means “bringer of victory”) comes from a poem by Callimachus. In the poem, Berenice promises her hair to Aphrodite if her husband returns from war safely. Egaeus may come from Aegeus, a legendary king of Athens who had committed suicide when he thought his son Theseus had died attempting to kill the Minotaur.

Haughtiness is arrogance and pride……meaning proud.

Sorry, I do not know the meaning of the 2 names.

No need to ask for forgiveness because your English is alright. Well done……

correction : Does anyone KNOW…….. :~)
