Alternative formsEdit


From Proto-Italic *merks, 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.[1]

However, in the 2020s, Nikolaev and Matasović independently proposed Indo-European etymologies for merx. Both derivations assume that the 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.



merx f (genitive mercis); third declension

  1. merchandise, commodity
  2. goods, wares


Third-declension noun (i-stem).

Case Singular Plural
Nominative merx mercēs
Genitive mercis mercium
Dative mercī mercibus
Accusative mercem mercēs
Ablative merce mercibus
