noun

Alternative form of frith (“a forest used for hunting; a (small) wood; wooded country; land covered mainly by brushwood”).

Origin

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.
