Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
The Gnomish Lexicon of the 1910s had G. gwithadr and gwithant “shuttle” based the early root ᴱ√gu̯iđ (GL/46).
Neo-Sindarin: Tolkien had a later root √WIR for “weave”, so I’d update these Gnomish words to ᴺS. gwirthar “shuttle” = √WIR + √THAR, (lit.) “weave-across”.
