Be careful not to confuse tortuous with torturous. These two words are relatives-both ultimately come from the Latin verb torquere, which means "to twist," "to wind," or "to wrench"-but tortuous means "winding" or "crooked," whereas torturous means "painfully unpleasant." Something tortuous (such as a twisting mountain road) might also be torturous (if, for example, you have to ride up that road on a bicycle), but that doesn't make these words synonyms. The twists and turns that mark a tortuous thing can be literal ("a tortuous path" or "a tortuous river") or figurative ("a tortuous argument" or "a tortuous explanation"), but you should consider choosing a different descriptive term if no implication of winding or crookedness is present.
