The line 'O say can you see …' starts with an 'O', not 'Oh'. While 'O' might appear as a dated form of 'Oh', it carries a distinct meaning. Examples like 'O Captain, my captain', 'O Pioneers', 'O Come All Ye Faithful', 'O Canada', 'O Brother Where Art Thou', 'O ye of little faith', and 'O Christmas Tree' all use the vocative 'O'—indicating direct address. When you say 'O Christmas tree', the 'O' shows you're speaking directly to the tree. The rest of the song reinforces this. (Your branches are lovely! You’re always wearing that dress of green!) The same applies to 'O Canada' and most anthems. Your school's song might begin with 'O [alma mater], your campus is beautiful, and we think you're great.'
'Oh' is more versatile. It can express emotions such as pain, surprise, or disappointment. For example, 'oh, man!' can convey various feelings, while 'O man!' is a direct call to a person, as in 'Hey, you there, man.'
Currently, 'oh' is typically written in lowercase and often followed by a comma, whereas 'O' is capitalized and stands alone, without a comma. However, the distinction between them wasn’t always so clear-cut, and they were once used interchangeably. Their meanings can sometimes overlap. When Juliet exclaims, 'O Romeo, Romeo, wherefore art thou Romeo?', is she calling out to him in her thoughts or expressing deep emotion? It's a bit of both. This blending of uses makes it tricky to draw a firm line between the vocative 'O' and other forms. Today, the vocative 'O' seems old-fashioned and is mostly found in classic poems and song titles.
...yeah, seriously. Thanks to LOLspeak, 'O' has managed to evolve and persist, though it’s no longer confined to its traditional vocative role. This flexible, adaptable 'O' continues to thrive, acquiring new meanings along the way, doing whatever it takes to remain relevant.
