A verb appearing as ᴱQ. tanta- “bounce, bound, rebound” in the Qenya Lexicon of the 1910s under the early root ᴱ√TṆTṆ (QL/93). The verb tante reappeared in the Early Qenya Grammar based on primitive ✶tṇt- {“dance” >>} “bounce” (PE14/58). See also the transitive variant tanta- from this same period “dance (tr.), dandle, wave” (QL/94).
Neo-Quenya: As we have no better options for “bounce”, for purposes of Neo-Quenya I would retain ᴺQ. tanta- “to bounce, bound, rebound” based on the Neo-Root ᴺ√TANAT; I would use it both transitively and intransitively, with distinct past forms tantane “bounced [something]” and tanante “bounced [self]”. This does conflict with the 1960s verb Q. tanta- “to play a harp”, but I prefer 1930s ᴹQ. ñanda- “to harp” instead. For other “dance” verbs see Q. lilta-.
In a 2025-01-25 post to the Vinyë Lambengolmor Discord Server (VLDS), Luinyelle this word might also mean “swing (intr.), sway, dandle, wave”.
A root appearing as ᴱ√TṆTṆ in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. tanta- “bounce, bound, rebound”, and ᴱQ. tantl “shuttle” (QL/93-94). It also had derivatives in the contemporaneous Gnomish Lexicon like G. tanta “a dance” and G. tinta- “dance” (GL/69-70). The verb ᴱQ. tanta- “bounce” also appeared in the Early Qenya Grammar of the 1920s with the same derivation, along with other verbs like ᴱQ. tantilta- “hop” and ᴱQ. tantya- “set bouncing” (PE14/58). In much later writings from around 1968, Q. tanta- was given the gloss “to play a harp” (VT41/10).
Neo-Eldarin: I prefer 1930s ᴹ√ÑGAN(AD) as the basis for “harp” words, so I’d update early ᴱ√TṆTṆ to ᴺ√TANAT “bounce” to salvage early “bounce” words, but I’d use later ᴹ√LILT for “dance” words.
