From Proto-Italic *merks (compare Faliscan 𐌌𐌄𐌓𐌂𐌖𐌉 (mercui, dative), Oscan 𐌌𐌄𐌓𐌉𐌊𐌖𐌉 (merikui, dat.sg.), names of deities), of uncertain etymology. De Vaan relates this word to Mercurius, deriving them both from a root referring to various aspects of economics, which he presumes to have an Etruscan origin.
However, in the 2020s, Nikolaev and Matasović independently proposed Indo-European etymologies for merx. Both derivations assume that the simple -c- in the oblique cases was analogically levelled based on the nominative singular, as all velars merged to *-k- when immediately preceding the nominative singular *-s in Italic.
