A Doriathrin word meaning “forward” or “west”, derived from the root ᴹ√NIB (Ety/NIB). It could have developed from primitive forms like ✶nibon or ✶nibn(ǝ), with -on developing in the second example because [[ilk|[o] developed between a consonant and a final [n]]] in Ilkorin. As noted by Helge Fauskanger (AL-Doriathrin/nivon), the sense “west” probably developed from the meaning “forward” because the Elves thought of themselves as facing West when marking directions.
