History and Etymology for demo


by shortening

Combining form

combining form from Greek dêmos "district, country, people, common people, political district in Attica," of uncertain origin

Note: Greek dêmos has traditionally been linked with Old Irish dám "guests, company, retinue," Old Welsh dauu, glossing Latin cliens (hence, presumably, "member of a retinue"), Modern Welsh daw, dawf "son-in-law." However, the semantic discrepancy between the two etyma is significant, and Celtic *dāmo-/*dāmā- has more recently been explained as going back to *dōmo-, a lengthened-grade adjectival derivative of Indo-European *dom-o-s, "house, household." The further traditional link with Indo-European *deh2- "cut, divide" (whence Greek daíomai, daíesthai "to divide"; cf. tide entry 1), assuming a noun *deh2-mos meaning originally "part, division," is still possible, though it would be deprived of any support beside Greek.
