What does sinuate mean?
Sinuate means to move or extend along a winding path, following a succession of curves rather than proceeding in a straight line. The word is especially common in formal geographical and biological description: a river may sinuate across a plain, a coastline may sinuate around a bay, or a boundary may have a sinuous outline. Its visual and literary associations are gentle and graceful rather than abrupt, although it can also describe sharper, repeated bends. A related adjective, sinuate, describes something marked by a wavy edge or winding course. The word comes through Latin from the language of waves and curves. Compared with more familiar alternatives such as wind, curve, or meander, sinuate tends to sound more precise and elevated, making it especially effective in descriptive prose but less common in casual conversation.
To follow a winding or sinuous course.
"The stream sinuates through the meadow toward the river."
Used chiefly in formal and descriptive contexts; it can describe movement, a route, or an edge that follows a winding course.
Having a wavy outline, with a series of curves or indentations.
"The leaves have a distinctly sinuate margin."
Common in botanical and zoological description, especially for an edge or margin with inward-curving indentations.
A sinuate shape remembers a river: it advances by bending rather than travelling in a straight line.

Where does sinuate come from?
The English word derives from the Latin adjective sinuatus, meaning curved or winding, formed from sinus, a term associated with a bend or fold. It entered English through the verb sinuare, meaning to bend or curve. English later adapted the Latin participial form as an adjective with the meaning having a wavy or indented outline. Related English words include sinuous, sinusoidal, and sinuation, all preserving the Latin association with curves and wave-like movement.
