Time for a trip back in history—brace yourselves, as we're diving into the origins of a puzzling phrase you might've heard your folks or grandma utter: "Where does what in tarnation come from?"

This exclamation, often used in confusion, annoyance, or amusement, and hailing from the hills of Appalachia, is a more polite version of the old-fashioned "hell." But instead of jumping the gun, let's step back and examine its paved path to our everyday expressions.

Etymology of "Tarnation"
Our journey begins in the hearty, straightforward language of 19th-century American frontier dwellers. They shortened "eternal" to "etarnal," which then evolved into "tarnal" and finally, "tarnation."

You might be wondering, why the change? Frontier folks needed a milder term for their kids and ladies, leading to the substitution of "hell" with this 'family-friendly' stand-in.
Regional Origins

"Where does what in tarnation come from?" is like a child of Appalachia, born and bred among the region's hillfolk. The first recorded use of "tarnation" dates back to 1832 in a hymn by Washington-Irving, "Sometimes we pine for tarnation," hinting at the phrase's earlier oral usage.
Now, the "what in" part? That's a classic Southern suffix, adding emphasis or incredulity to a question. Think 'why in the world?' or 'who in the Sam Hill?' Same family, just a different member.
Evolution and Spread

By the 20th century, this earthy exclamation had spread from Appalachia and the American South to the wider nation. It's now found in everyday language, from grandma's tale to sitcoms and comic strips.
Just look at Nancycartwright's Krusty the Klown exclaiming, "Who put what in tarnation?!"; it's as American as apple pie, and probably just as confusing if you're not a native speaker.
Comparable Expressions Across Cultures

Now, let's cast a wider net. "Where does what in tarnation come from?" has cousins in other languages and cultures, too. Consider these:
- French: "D'où sort ceci?" (Where does this come from?)
- Spanish: "¿De dónde sale esto?" (Where does this come out of?)
- Italian: "Da dove viene questo?" (Where does this come from?)
- German: "Wo kommt das her?" (Where does this come from?)









Each translates to roughly the same meaning, expressing surprise, confusion, or irritation at an surprising or annoying situation.
Modern Usage and Idiomatic Evolutions
In modern English, "where does what in tarnation come from?" is increasingly used for comedic effect or rhetorical flourish, especially in storytelling. It's a bit like context-dependent punctuation, adding color and emphasis to conversations and narratives.
A less ornate, more contemporary version might be, "WTF?," but that's a tale for another day. Our dapper, early-20th-century grandpa loves his "What in tarnation?"—so let's keep that old-time charm alive!
So next time someone hollers, "Where does what in tarnation come from?," you can tip your hat to history and sagely nod, knowing the full, twisty backstory of this robust, earthy phrase. Now go forth, spread some historical enlightenment, and ponder no more—this is where the fun begins.
