An oldn-stem as evidenced by theKluge's law variant*makkô, perhaps fromProto-Indo-European*móg-ō, from*meg-,*mog-(“to knead, work”) (alternatively*mag-,*meh₂ǵ-,*meh₂ḱ-; various sets of cognates and meanings suggested). In any case from the same root as*makaz(“fitting, suitable, convenient, comfortable”); see there for the root reconstruction.[1]
