helixn.

Brit.

/ˈhiːlɪks/,

/ˈhɛlɪks/, U.S.

/ˈhilɪks/

Forms: Plural helices /ˈhɛlɪsiːz/, helixes.

Etymology: < Latin helix, < Greek ἕλιξ anything of spiral form.

1. Anything of a spiral or coiled form, whether in one plane (like a watch-spring), or advancing around an axis (like a corkscrew), but more usually applied to the latter; a coil, a spiral, as an electromagnetic coil of wire, the thread of a screw, a tendril, etc. In Geometry, the curve formed by a straight line traced on a plane when the plane is wrapped round a cylinder; more generally, a curve on any developable surface (e.g. a cone) which becomes a straight line when the surface is unrolled into a plane; distinguished from spiral, which is applied only to plane curves.
