'orchid' originates from the Greek word 'orkhis', where 'orkhis' meant 'testicle', referring to the shape of the root tubers in some species.

'orkhis' transformed into the Latin word 'orchis', and eventually became the modern English word 'orchid'.

Initially, it referred to the shape of the root tubers, but over time it evolved into its current meaning of a plant family known for its flowers.
