interdialectal

adj

1. (not-comparable)Between dialects.

   “interdialectal variation”

   “Wagner argues that most of the Sardinian forms presented above are interdialectal loans from lóssi̯a (8: Milis). Vendors from Milis and its surroundings, where reeds and rushes are common, would have travelled the island to sell their woven mats, thus dispersing their word for it.”
