Where it comes from
Borrowed from Scots firth, furth, from Northern Middle English fyrth, from either or both of Old English ford and Old Norse fjǫrðr (“firth, fjord”), from Proto-Germanic *ferþu, *ferþuz (“inlet, fjord”), from Proto-Indo-European *pértus (“crossing”), from *per- (“to carry forth”) + *-tus (suffix forming action nouns from verb roots). The English word is a doublet of fjord, ford, port, and fjard.
