Our name is Latin:
cybaea (latin), ae, f.: trading vessel; a transport, cargo, or merchant ship.
It refers to a merchant ship of Greek origin that was common in the Mediterranean. Mentioned in Latin only by Cicero in the orations against Verres, it is described as
most beautiful and richly adorned.
We prefer the translation “trading vessel”—isn’t that what every company is? Pronunciation was probably with an initial [k] sound but everybody uses a [s] sound, like “cyber-”, so that is that we go with, with the final ‘e’ and ‘a’ each pronounced separately.
