In Norwegian, the circumflex differentiates "fôr" "lining, fodder" from the preposition "for". From a historical point of view, the circumflex also indicates that the word used to be spelled with the letter "ð" in Old Norsefor example, "fôr" is derived from "fóðr", "lêr" 'leather' from "leðr", and "vêr" "weather, ram" from "veðr" (both "lêr" and "vêr" only occur in the Nynorsk spelling; in Bokmål these words are spelled "lær" and "vær"). After the "ð" disappeared, it was replaced by a "d" ("fodr, vedr").
