 The major theories make Levico derive from Celtic terms such as "leoug", "leak" or "lewa", signifying "border post/boundary marker", or from the barbaric gentilic "Letta", from which came "Levi vicus" then contracted into "Levicus", or from the Latin "(praedium) Livicune" ("Livius' farm", then vulgarised into "Lievigo" and "Levigo") or "Laevus vicus", "village left [of the river]".The Latin interpretations are the ones most agreed with, given the abundance of Latin terms in the topography of the municipality (such as Furo, from "forum").Successive Lombard presence is also cited in various documents and found in some toponyms, such as "Guizza" (from "wizza", communal grazeland).
