onot-

verb. *to count up, reckon, [ᴹQ.] to count up, *reckon

A verb implied by the nouns onótimo and onótië (MR/49, 57), presumably “✱reckoner” and “✱reckoning” respectively, so the verb onot- likely means “✱to reckon”. It is clearly a combination of o- “together” and not- “count”. In The Etymologies of the 1930s ᴹQ. onot- was glossed “count up” and was derived from the root ᴹ√NOT “count, reckon” (Ety/NOT).

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. qoto- “count up; reckon; account, call up; think, consider” under the early root ᴱ√QOTO (QL/78), and ᴱQ. tasta- “reckon” under the early root ᴱ√TAÞA “count” (QL/90).
