scotia
Synonym discussion
Sense: noun/1
These terms all describe decorative strips in classical architecture, but they differ in shape and position. A scotia is a concave (inward-curving) molding found at the base of a column, usually between two convex bands. A torus is the opposite — a convex, outward-curving molding that often sits directly below the scotia in a column base. Molding is the broad, everyday category word for any continuous decorative band along a building surface; scotia and torus are both specific subtypes. Cyma is another curved molding (either S-shaped), but it appears higher up, near the top of a column or on a cornice, not at the base. In practice, you might say 'the scotia curves inward like a dark groove, while the torus below it bulges outward like a rounded cushion.'

Etymology
The English word 'scotia' comes directly from Latin 'scotia', which was borrowed from Greek 'skotia' (σκοτία), literally meaning 'a dark molding'. The Greek root 'skotos' (σκότος) means 'darkness'. The name likely refers to the deep shadow that the concave carving casts along the column base — a striking visual effect that classical architects deliberately used to add depth and contrast to the base of a column.
