Etymology of SEMIDIURNAL
The word "semidiurnal" is derived from two Latin roots: "semi", meaning half, and "diurnus", meaning daily or relating to the day. The combination of these roots forms "semidiurnus", which translates to "half daily" or "half of a day". This term was later anglicized into "semidiurnal", which refers to something occurring twice a day, often describing the tides or astronomical phenomena with a period of approximately 12 hours.
