zephyr

The word "zephyr" has its origins in ancient mythology and language. It comes from the Latin word "zephyrus," which in turn is derived from the Greek word "zéphuros" (Ζέφυρος). In Greek mythology, Zephyrus (or Zephyr) was the god of the west wind and was considered the gentlest of the winds. This association with gentle breezes is why "zephyr" came to mean any light or mild westerly wind. Over time, the term evolved to generally refer to a gentle, mild breeze in English. The first known use of "zephyr" in English dates back to the 16th century.
