What does sinuation mean?
Sinuation is a formal noun meaning a bend, curve, or winding course, or the process of following such a shape. It can describe the movement of a road or river, the changing direction of a line, or a rhetorical passage that develops a complex argument rather than proceeding directly. The word is related to sinuous, meaning curved or winding, and gives particular emphasis to an undulating path or repeated change of direction. Although accurate and sometimes useful in geometry, geography, and figurative writing, sinuation is much less common in everyday English than bend, curve, twist, or meander. It is especially appropriate when a description should convey an irregular or serpentine course rather than a single simple bend.

Where does sinuation come from?
Sinuation derives from Latin sīnuātiōn, a noun formed from sīnuāre, “to bend” or “make winding.” The Latin root sīnus also underlies English sinus and the related words sinuous and sinuate. The borrowing preserves the central sense of bending or curving, which was later extended to winding courses and figurative rhetorical development.
