Synonym discussion
Sense: adjective/1
All three words describe something that branches or spreads from a centre, but they differ in scope and technicality. 'Star-shaped' is the most common and neutral term for everyday use — a star-shaped cookie, a star-shaped badge, a star-shaped leaf. 'Stellate' is a technical term mainly found in botany (a stellate hair on a leaf surface), biology (stellate cells), and crystallography; it sounds out of place in ordinary conversation. 'Radial' focuses on the geometry of rays or spokes extending from a centre rather than the pointed, star-like tips. A radial tyre has cords arranged in a circle, not a star pattern. Use 'star-shaped' for most situations; use 'stellate' only in scientific writing; use 'radial' when you mean 'arranged like the spokes of a wheel' rather than 'like a star's points'.

Etymology
Formed in Middle English by combining the noun 'star' (from Old English 'steorra') with the suffix '-like' (from Old English 'gelic', meaning 'having the form or quality of'). The word has been used since at least the 1500s to describe anything that resembles a star in shape, brightness, or arrangement.
