Adjective
double-marking (not comparable)
(linguistics) Of a language: such that the grammatical marks showing relations between the constituents of a phrase tend to be placed on both the heads (or nuclei) of the phrase in question, and on the modifiers or dependents.
In some languages, there is double-marking of a word as both genitive (to indicate semantic role) and another case such as accusative (to establish concord with the head noun). Source: Internet
