helicale

Helicale is a term used to describe something related to or forming a helix, a three‑dimensional curve that winds around a cylinder with a constant pitch. In many contexts, objects or structures described as helicale exhibit a spiral path or coil as they extend along an axis.

In English, helicale is not a standard technical word. The more common adjectives are helical or helicoidal, used to characterize objects, surfaces, or motifs that follow a helical geometry. Some languages adopt forms similar to helicale as loanwords or direct translations, but in English technical writing the preferred terms are helical, helicoid, or helix-related.

Applications and examples can be found across disciplines. In biology, the alpha-helix is a common secondary structure in proteins, and DNA is organized as a double helix. In chemistry and materials science, helical motifs appear in molecules and supramolecular assemblies. In engineering and design, screws, springs, and helical staircases embody the geometric idea. Helical forms also influence architecture and art, where spiral ramps or twisted columns convey motion and complexity.
