'calyx-shaped' originates from the word 'calyx,' which comes from the Greek word 'kalyx,' meaning 'husk' or 'covering.'

'calyx' was adopted into Latin as 'calyx,' and eventually became part of the English language, forming the compound adjective 'calyx-shaped.'

Initially, 'calyx' referred to the outer covering of a flower, and 'calyx-shaped' has retained this meaning, describing anything that resembles this structure.
