petal

The word 'petal' entered English in the early 18th century from the Latin 'petalum'. The Latin term was a direct loan from the Greek 'petalon', which meant a thin, spread-out object like a leaf or a plate of metal. This Greek word is derived from the verb 'petannynai', meaning 'to spread out' or 'to unfold', a concept perfectly describing the form and function of a flower's petal. Thus, the modern botanical term retains the ancient sense of a broad, flat, and delicate structure.
