Modern English greetings were once bound by strict class etiquette. In late nineteenth-century Britain and North America, meeting an unfamiliar peer required the ritualistic "How do you do?" Crucially, this phrase was never an inquiry into someone's health or emotional well-being. It was a formal spoken token that required no answer other than the identical question repeated back: "How do you do?" Treating it as a literal question broke etiquette immediately.
That rigid scaffolding began cracking with the spread of the telephone in the late 1870s. Alexander Graham Bell famously advocated for "Ahoy!" as the standard telephonic greeting, borrowing the maritime hail. Thomas Edison pushed hard for "Hello", an obscure variant of the Middle English "hallow," previously used to shout across hunting fields or express surprise. Edison won. By the 1920s, "hello" had shifted from a telephone-specific shout to an accepted face-to-face greeting, displacing elaborate polite inquiries.
The transition accelerated throughout the post-war decades of the twentieth century. Democratic workplace cultures, egalitarian social shifts, and casual suburban interactions systematically dismantled ornamental etiquette. "Good day" receded into historical novels and regional dialects, leaving a streamlined set of daily options that continue to contract in digital environments.
