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!
brant
adjective. cooked, done; overdone
brant
noun. bow (for shooting)
brantha-
verb. to scorch
A verb in the Gnomish Lexicon of the 1910s appearing as G. brantha- “scorch”, related to (and possibly derived from) G. brant “cooked, done; overdone” (GL/24).
Neo-Sindarin: I recommend restoring this confluence of Gnomish cooking-related words in Neo-Sindarin based on a Neo-Root ᴺ√BRATH “cook”, and would adapt this word as ᴺS. branna- “to scorch” to better fit Sindarin phonology.
branc
noun. bow (for shooting)
branta
noun. bow (for shooting)
tortha-
verb. to scorch
A verb in the Gnomish Lexicon of the 1910s glossed “scorch” (GL/71), probably based on the early root ᴱ√TORO (QL/94).
An adjective appearing as G. brant “cooked, done” in the Gnomish Lexicon of the 1910s, with the more specific connotation of “overdone”, perhaps due to the influence of the verb G. brantha- “scorch” (GL/24).
Neo-Sindarin: For purposes of Neo-Sindarin I retain the Neo-Root ᴺ√BRATH “cook” along with its related derivatives, so I would retain ᴺS. brant as well. For “cooked” without the connotation of “overdone”, I would use the passive participle brannen of the verb ᴺS. brath- “to cook”.
