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!

Gnomish

pectha

noun. plume

The word G. pectha “plume” appeared in the Gnomish Lexicon of the 1910s, along with G. pecthon “plume, feather” (GL/63-64), clearly cognates of ᴱQ. pekte “plume” under the early root ᴱ√PEKE (QL/73).

Neo-Sindarin: For many years, Neo-Sindarin writers used ᴺS. pess for “feather” as the analog of word Q. quessë, which Tolkien used in the 1930s-1960s. Hialmr added this Neo-Sindarin word to the VQP (VQP) in 2015, but it was likely floating around for much longer. For “plume”, I would use an augmentative form: ᴺS. pesson “plume, (great) feather”. In 2024, a native Sindarin word S. laud “feather” was published in PE23; see that entry for discussion. Pess “feather” has been a part of Neo-Sindarin for so long that I think it is reasonable to keep using it, but if you want to stick to Tolkien’s own words, laud is probably better.
