Per De Vaan, by syncope from *praedicō, *praedicōn-, with the same prefix and root as the verb praedicō (“proclaim, declare publicly”) from prae- + dicō (“dedicate, assign to”) combined with the agent noun suffix -ō, -ōn-.[1] An alternative proposal derives it by syncope from *praevocō, *praevocōn-, from prae- and the root of the verb vocō (“call, invoke”).[2]
