Synonym discussion

Sense: noun/1

A cone has a circular base that narrows smoothly to a single point along straight sides — the defining feature is the continuous curved surface. A pyramid also narrows to a point, but its base is a polygon (usually a square) and its sides are flat triangles, not curved. A spire is a tall, narrow, pointed structure built on top of a church or building — it describes an architectural element rather than a general shape category. A taper is not a shape at all but a process: it refers to the gradual narrowing of an object toward one end, like the tip of a pencil or a candle. For example: 'The tower roof forms a cone' (circular, smooth sides); 'The ancient temple roof forms a pyramid' (flat triangular sides); 'The needle had a gentle taper at the tip' (gradual narrowing).

Etymology

GreekLatinFrenchEnglish

The word 'cone' comes from the Greek 'konos', meaning 'pine cone' or 'geometric cone'. It passed into Latin as 'conus', then into Old French as 'cone', and finally entered English around the 1500s. The geometric and pine cone meanings have coexisted from the start.
