domainn.

Brit.

/də(ʊ)ˈmeɪn/, U.S.

/doʊˈmeɪn/,

/dəˈmeɪn/

Forms: Also Middle English domayne, 1600s domaine.

Etymology: < modern French domaine (1611 in Cotgrave), for earlier French demaine , Old French demeine < Latin dominicum , in medieval Latin = ‘proprietas, quod ad dominum spectat’, substantive use of dominicus of or belonging to a lord, of the nature of private property, proper, own. See demesne n., which is another form of this word. Old French domeine, demeine, did not come down from classical Latin dominium lordship, ownership, property, for that could have given only an Old French domein, demein; it is supposed that classical Latin dominicum passed in Romance and Old French through the stages *domenio, domenië, domeine, demeine: compare canonicum, *canonio, canonië, canoine, chanoine. But, in the intermediate stage, the form of the word naturally suggested its identity with classical Latin dominium, which consequently appears, beside the original dominicum, as the Latin equivalent in mediæval documents; the latter have also domanium formed on the vernacular. The o was in Old French regularly weakened to e, demeine, whence late Anglo-Norman & English demesne; in domaine the o is restored after Latin; in French, domaine is now (since c1610) used in all senses; but in English, demesne has been traditionally retained in the legal use, and in senses immediately derived from it, though the two forms overlap.

a. eminent domain: ultimate or supreme lordship; the superiority or lordship of the sovereign power over all the property in the state, in accordance with which it is entitled to appropriate by constitutional methods any part required for the public advantage, compensation being given to the owner. A term chiefly used in International Law, and in the Law of the United States of America.
