Examples:
- One oh two Main Street
- Four oh seven PM
- Biology one oh one
- Eight six seven, five three oh nine
- Four oh four: Not found
Not just a US thing, so I hope this is okay to ask here. I have just never encountered this is any language other than English. Is it simply that O and 0 look similar, and that “oh” has fewer syllables than “zero”? I have not heard a good explanation from coworkers who I’ve asked.
It’s shorter than saying zero and it’s only ever used where context makes the it obviously not the letter. Also, almost all of the other digits are single syllables too. Seven is arguably (I’m no linguist) the only other multi-syllable digit and I think it gets a pass because it’s barely more than a single syllable unless you emphasize it.
