A hypothetical Sindarin-only Neo-Root coined by Paul Strack in 2023 to justify the retention of the Gnomish would thim “milk” from the 1910s.

A neologism for “thimble” coined by Shihali in 2020-10-05 on the Vinyë Lambengolmor Discord Server (VLDS). Shihali originally based this word on √LEP + ✶-mā without metathesis where pm became pp, but I prefer to assume it is simply from strengthened ✱leppā.
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
thim
noun. milk (after separation)
A word appearing as G. thim “milk, after separation” in the Gnomish Lexicon of the 1910s, clearly related to the verb G. thin- “skim” (GL/71-72).
Neo-Sindarin: Although there are no other related words in Tolkien’s later writings, there are also no other alternatives for “milk” in the Sindarin language branch, so I would retain ᴺS. thim “milk” for purposes of Neo-Sindarin. I would use it especially for milk separated from cream. It might be derived from an ancient form such as ✱thimbē from a Neo-Root ✱ᴺ√THIM.
thimli
noun. whistle, piccolo
thimpa-
verb. to play a flute or whistle
thimp
noun. the stop on a flute
thimpion

A rejected name appearing only on the earliest Silmarillion map from the late 1920s or early 1930s, possibly a fortress of Morgoth according to Christopher Tolkien (SM/223). Its meaning is unclear.
