“root” vs. “route”
Use "root" for a plant's underground structure, an origin or cause, a mathematical operation, or the verb meaning to cheer or search, and save "route" for anything describing the course a traveler, vehicle, or package follows to reach its destination.
root
"Root" is a noun and verb covering several related senses: the underground part of a plant that anchors it and absorbs nutrients, the origin or source of something (the root of the problem), a mathematical operation (a square root), and, as a verb, to cheer for a team ("root for the home team") or to search around thoroughly ("root through a drawer"). It comes from Old Norse "rot," a Germanic word for the underground plant structure, which extended metaphorically to mean origin or foundation.
route
"Route" names the course you follow to get somewhere — a bus route, a hiking route through the hills — and doubles as a verb for directing something along that course, as when a package gets routed through several depots before delivery. Its Old French ancestor, also spelled "route," traces to Latin "rupta via," a "broken way," since early paths were often literally cut through untouched wilderness, tying "route" to the same Latin root, "rumpere" (to break), that also gives English "rupture" and "erupt."
The real distinction
"Root" and "route" come from entirely different linguistic families — "root" from a Germanic word for underground plant structure, "route" from Latin "rupta," a broken or forced path — and despite sounding alike in many American accents (though British English typically pronounces "route" closer to "root" as well, adding to the confusion), the two describe unrelated concepts: one is about plants, origins, and mathematics, the other is about paths and travel. Botany, origins, math, and enthusiastic cheering all call for "root," while anything involving a path, way, or course of travel calls for "route." That cheering sense of "root" ("I'm rooting for you") deserves a special mention, since it has no connection to plants whatsoever — it likely derives from an unrelated dialectal use connected to pigs "rooting" around enthusiastically for food, extended figuratively to enthusiastic support. "Route," meanwhile, appears constantly in navigation, delivery, and transportation contexts, and its connection to "rupture" is a genuinely useful memory anchor, since a route was historically understood as a path violently broken through wilderness rather than a naturally existing trail, a vivid image quite different from anything botanical.

Memory trick
Remember "root" through its underground, earthy meaning — plants, origins, foundations, all things that go down and take hold, much like the everyday phrase "put down roots." For "route," hold onto its surprising kinship with "rupture" and "erupt" — a route was historically a path violently broken through untamed land, a far more dramatic image than a quiet garden root. If the sentence is about plants, origins, math, or cheering, choose "root"; if it's about traveling from one place to another along a set path, choose "route." The pronunciation overlap between British and American English adds an extra layer of difficulty here, so when in doubt, leaning on the sentence's actual subject matter rather than sound is always the more reliable strategy.
