Hi,
Is round a shape? Or an adjective that describes a shape? At the moment, I'm thinking it is, and all the sites I've looked at seem to agree, but it's been argued with me that round only refers to a shape, and is not actually one.
As an adjective, 'round' describes a shape. However, as a noun, 'round' has a number of meanings, some of which relate to shape. eg a bullet is often referred to as a round, because of the shape. As a verb, 'to round' something often means to produce a round shape.
Best wishes, Clive
