Etymology: "Uchronia" was coined in French on the model of "utopia," a word Thomas More invented in 1516 by punning on Greek roots meaning "no place." The new coinage swapped the spatial prefix for a temporal one: "ou" (not) joined "khronos" (time), giving a word for a "no time" that is, in effect, an other time. The "-ia" ending is the same suffix that closes "utopia," which is why the two words look like siblings. The result is a deliberate pun on the older term. Where utopia imagines a good society in a place that does not exist, uchronia imagines a different history in a time that never happened. Both are built on the same Greek negation and the same pattern, so the new word announces its debt to "utopia" in its very shape.
