Arden is a place name and a surname that comes from Celtic *ardwo meaning “high”. It was used as the name of a forest in William Shakespere’s play As You Like It (roughly around 1599), as well as being the name of a real forest in Warwickshire, England. Arden was also the maiden name of Shakespeare’s mother, Mary Arden.
Another possible meaning I’ve seen for Arden is “eagle valley” which comes from Old English earn (eagle) and dun (valley).
Arden is also a word in Spanish, the third person plural of arder meaning “to burn”, derived from Latin ardere.
