'zephyr' originates from Greek, specifically the word 'Zephyros', where 'Zephyros' was the god of the west wind.

'Zephyros' transformed into the Latin word 'zephyrus', and eventually became the modern English word 'zephyr'.

Initially, it referred to the god of the west wind, but over time it evolved into its current meaning of 'a gentle breeze'.
