📚 Etymology▼
The conjunction 'o' comes from the Latin word 'aut' (meaning 'or'). The accent was a late addition in Spanish orthography, introduced purely for visual clarity between numbers, but it has since been removed from standard use.
First recorded: The base word 'o' dates back to early Romance languages; the accented form 'ó' became common practice in Spanish printing and handwriting during the 18th to 20th centuries.
