The Romic Fùiglafiòrdhàgh is derived from Old Norse fugl, meaning "bird", and fjǫrðr, meaning "a lake-like body of water meant for passage or ferrying". The additional suffix "-àgh" is an Old Romic plural suffix; it is unclear why this was added, but its earliest recorded usage was in 1576. The English Fowlfjords is derived from Old English Fowele fiord, which later morphed into the current Fowfljords. It has the same Old Norse etymological source as Fùiglafiòrdhàgh.
