The name may have been derived from the Welsh ap Ridel, meaning "son of Ridel", an ancient Welsh name from the parish of Lillieslead, County Roxburgh. Variations of the Welsh form are ap Rhiddid, meaning "son of Rhiddid", or even ap Redith, which means "son of Redith", a short form of Meredith. If so it has its roots in the personal name Maredudd, of which the Old Welsh form is Morgetiud, of which the first element may mean "pomp" or "splendor" and the second, iudd, meaning "lord". That being the case, Priddy may mean or imply "son of splendid lord" or simply "son of lord."
It is also possible that Priddy was derived from the personal name Predyr or Peredur (perhaps from Old Welsh peri ‘spears’ + dur ‘hard’, ‘steel’), which was borne, in Arthurian legend, by one of the knights of the Round Table.
The name may have been derived from occupational trade, from the Welsh prydydd, meaning "bard".
