The prefix "de-" in English is of Latin origin, derived from the Latin word "de", which means "down" or "downward". It often indicates removal, separation, or negation.
The noun "fog" is derived from Old English "fogge", which referred to a dense, misty vapor or cloud typically found near the ground. The origin of "fogge" is uncertain, but it may be related to the Old Norse word "fok", meaning "snowdrift" or "flake".
