Etymology 2Edit

English O, o is attested in William Tyndale's 1525 New Testament Translation, as a translation of Ancient Greek ὦ, Latin o. (Compare the Old English particles èalà, æàlà, ǽlà, hèlà.) In Middle English, O is found in Acts 13:10, Romans 9:20 and Galatians 3:1, and ò is found in Romans 2:1,3, of John Wycliff's Newe Testament (1382). Compare la (a particle for introducing a statement or expressing surprise), from Old English; compare also English lo, oh.

Compare the Old Saxon gloss o (950s) of the Lambeth MS (957) of the Gallican Psalter and the ó, o (post-1000) of the Durham Hymns, regularly seen in the redundant forms "o eala þu" and "ó eala þu" by proper names.

Compare also the Anglo-Norman O (about 1200) of the manuscripts of Saints Juliana and Katherine, and other religious writs.

ParticleEdit

O

1. (grammar) The English vocative particle (usually in upper case), used for direct address, including in translations from languages which have the vocative case.
   • 1525, Tyndale's translation of Romans 2.1,3:

     Therefore arte thou inexcusable o man whosoever thou be that iudgest. For in that same where in thou iudgest another, thou cõdemnest thysilfe. For thou that iudgest doest evẽ the same silfe thynges. […] Thynkest thou O man that iudgest them which do soche thyngs and yet dost evẽ the very same, that thou shalt escape the iudgemẽt of God?

Usage notesEdit

In native Latvian words (and in some older borrowings), o represents the sound of IPA [uə̯] (e.g., otrs [uə̯tɾs]). In more recent borrowings, it represents the original sound of the word, i.e. [o] or [oː] (e.g., opera [oːpeɾa]).
