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!
Early Primitive Elvish
kanga
root. weave
kaŋa
root. weave, twine
A root appearing in the Qenya Lexicon of the 1910s as ᴱ√KANGA “weave” with various derivatives of similar meaning (QL/45), but the actual root probably had medial Ŋ as with ᴱ√KAŊA “twine” appearing later in that same document (QL/98). There are a number of probably-related forms in the contemporaneous Gnomish Lexicon starting with either cang- or cing-, such as G. cang “tangled”, G. cingra “plaited”, and G. cing(win) “spider” (GL/25-26). There are no signs of this root in Tolkien’s later writing, but I think it is worth positing a Neo-Eldarin root ᴺ√KANGA “tangle” to salvage various Gnomish words having to do with tangles and confusion.
Early Quenya
kanga-
verb. to weave, spin
A verb in the Qenya Lexicon of the 1910s appearing only in its 1st sg. form kangin “I weave, spin” under the early root ᴱ√KANGA (QL/45).
Middle Primitive Elvish
lan
root. weave
lanya- (2) vb. "weave" (LAN)
