59 Greek Baby Girl Names Starting With Letter O

Baby girl names that start with O have an ornate literary history. O is the fifteenth letter of the Latin alphabet and emerges from the Phoenician ‘ayin’ meaning ‘eye’ (1). The letter was adapted into Greek as the omega for the long sound, large O, and as the omicron for the vowel form, small O.

In English, the long and short O have distinct sounds based on their origin. The long O in English derives its sound from the Old English long O and thus is a diphthong with the complex sound ‘ou’. This is reflected in Ophelia meaning ‘help,' which is pronounced as ‘ou-fil-ja’. The short O derives its sound from the Middle English short O and thus is either more open and lower or closed and rounded depending on which consonant it is paired with. This is reflected in Olga, which means ‘holy,’ pronounced with an open sound, ‘ol-ga.' However, in Spanish, the short O becomes ‘ue’.

Feminine O names such as Olivia and Odalys are among the top 1000 names in the US (2). Additionally, names like Odette, meaning ‘wealth’ in German, or Octavia, meaning ‘eighth’ in Roman, and O-girl names have gained fame and favor in both fiction and real life. So delve into this list of popular girl names starting with O with original and optimistic meanings to find one you like.
