alfuilin

noun. large white sea-bird, albatross, †swan

The noun ᴱN. alfuilin was “used of several large white seabirds, especially the albatross” in the Early Noldorin Dictionary of the 1920s, an elaboration of ᴱN. alf “swan”. In the Gnomish Lexicon of the 1910s, G. {alcothil >>} alfuil simply meant “swan” (GL/19), and the word alfuilin appeared with that gloss in a couple of other word lists (PE13/109, PE13/136) before becoming “albatross”.

Neo-Sindarin: I’d adapt this word as ᴺS. alfuil “albatross, large white seabird” for purposes of Neo-Sindarin, perhaps originally with the sense “✱swan of the seaweed”.
