mer (French)
Where does "mer" come from?
The French word 'mer' originates from the Proto-Indo-European root '*móri', meaning a sea or wetland, which evolved into the Latin 'mare'. While most Romance languages kept the word masculine, 'mer' uniquely became feminine in Old French, likely influenced by the gender of its conceptual opposite, 'terre' (land). This ancient lineage connects the modern word directly back through Middle and Old French to its prehistoric roots.
