A variant word for “thirteen”, a combination of yunquë “twelve” and enta “one more” (VT47/15). It also appeared as yunquente with an e (VT47/40). Compare also nel(e)quë “thirteen”.
Neo-Quenya: For purposes of Neo-Quenya, I think there is an interesting possibility that this word is the basis for duodecimal “teen” words, such as ✱yunquatta “twelve and two”, ✱yunquenel “twelve and three”, ✱yunquecan “twelve and four”, ✱yunquelempe “twelve and five”. I would follow these with [ᴹQ.] nahta “eighteen”, ✱nahtenta “eighteen and one more”, ✱nahtatta “eighteen and two”, ✱nahtanel “eighteen and three”, ✱nahtacan “eighteen and four”, ✱nahtalempe “eighteen and five” and finally [ᴹQ.] yurasta “twenty four = ✱double twelve”, the duodecimal equivalent of “twenty”. This is all quite speculative, however.
yunquenta cardinal "thirteen" (12 and one more) (VT47:15), variant yunquentë (VT47:40), compare entë #1.
