"Tortuous" = winding, full of twists and turns, or deviously complex; "torturous" = causing great pain or suffering, like torture.
Adjective: (1) physically: full of twists and curves (a tortuous road); (2) figuratively: excessively complex, convoluted, indirect (a tortuous argument, a tortuous process). From "tortus" (twisted, bent).
The road up the mountain was tortuous — seventeen hairpin turns in less than five kilometers.
The contract was so tortuous in its language that even the lawyers needed days to interpret it.
She navigated the tortuous bureaucratic process with patience and meticulous documentation.
Adjective: causing great pain, anguish, or suffering, like torture. "A torturous wait" = an agonizing wait. "A torturous experience" = an experience causing intense suffering. Directly related to "torture".
The waiting was torturous — three hours without any news from the surgical team.

For someone who hates crowds, rush-hour subway travel is an absolutely torturous experience.
Common mistake
Using "torturous" to describe something complex or winding: "a torturous legal process" should be "a tortuous legal process" (full of complications and twists, not necessarily painful). Context determines which is correct: if the road is full of curves, use "tortuous". If the driving experience was agonizing, use "torturous".
Trick to remember it
TortURous contains TORTURE inside it. If you can replace it with "like torture" or "agonizing", use TORTUROUS. TortUOUs (without the R from TORTURE) = winding, full of curves. Substitution trick: replace with "winding/convoluted" — if it works, use TORTUOUS. Replace with "agonizing" — if it works, use TORTUROUS.
Quick rule
Tortuous = winding / convoluted (road full of curves, complicated process). Torturous = agonizing / like torture (causing great suffering).
Did you know?
Both words come from the same Latin root "torquere" (to twist, to wring). From this root also come: "torque" (rotational force in physics), "contort" (to twist out of shape), "extort" (to obtain by force), and "distort" (to twist away from the original). English has a rich family of words built around this Latin root.
