Ona is the Lithuanian form of the name Anna, which itself originates from the Hebrew name Hannah, meaning "grace" or "favor." In Lithuanian, Ona (pronounced OH-nah) has been used for centuries and remains a traditional given name. The spelling reflects Lithuanian phonology, where the letter 'O' is pronounced as a long open 'o' sound. As a female name, Ona is a diminutive-lacking standard form, not a pet name. While not as common internationally as Anna or Hannah, Ona has enduring popularity in Lithuania and among Lithuanian diaspora communities. Key facts include: meaning "favor" or "grace"; origin: root of Hannah; type: female given name; chief usage: Lithuania.
