From Wiktionary, the free dictionary
Perhaps from Proto-Indo-European *mr̥-né-h₂-ti, nasal infix present of *merh₂- (“to crumble, destroy”); if so, cognate with Ancient Greek μάρναμαι (márnamai, “to fight”) and possibly Sanskrit मृणाति (mṛṇāti, “to crumble”) and Old Norse merja (“to hit”),[1] though the latter two may have other etymologies.
