"dairy farm," now surviving, if at all, as a localism in East Anglia or Essex, it was once the common Old English wic "dwelling place, lodging, house, mansion, abode," then coming to mean "village, hamlet, town," and later "dairy farm" (as in Gatwick "Goat-farm"). Common in this latter sense 13c.-14c. The word is from a general Germanic borrowing from Latin vicus "group of dwellings, village; a block of houses, a street, a group of streets forming an administrative unit" (see vicinity). Compare Old High German wih "village," German Weichbild "municipal area," Dutch wijk "quarter, district," Old Frisian wik, Old Saxon wic "village."
