A deleted verb from the Gnomish Lexicon of the 1910s glossed “to stretch, extend in length, trail” (GL/53), the equivalent of ᴱQ. lenu- “stretch” under the early root ᴱ√LENE “long” from the contemporaneous Quenya Lexicon (QL/53). In the Gnomish Lexicon, Tolkien also had G. lenu- as a possible equivalent to G. lentha- “approach”, but this second instance of lenu- was marked with a “?” (GL/53).

A rejected word for “length, distance” in the Gnomish Lexicon of the 1910s based on G. len “long” (GL/53).
Neo-Sindarin: For purposes of Neo-Sindarin, I would use ᴺS. annas for “length” based on later S. and “long”, but for “distance” I would use attested S. haered.
