Etymology Opfikon is formed with the place name suffix -(i)kon/-(i)ken, that is widely spread in the area of the cantons of Zürich, Argovia and Lucerne and that has been merged from the suffix -ing- ("followers of the mentioned one") and the word hof ("landed estate") in the dative plural form, used as a locative. This origin is yet more obvious at the congenerous place names ending in -(i)kofen, frequent in the cantons of Bern, Solothurn, and also in Thurgovia; place names of this formation are dated to the 7th/8th century. The first part of the name traces back to an anthroponym *Opfo, that, however, as such is not on record and is regarded either as a short form of a name like Otfried or something similar or as a formation from a supposed stem *upp-, forming names in west Germanic,
