lanta- (2) "fall" (DAT/DANT (TALÁT), Narqelion, VT45:26, VT49:54); lantar aorist tense pl. (Nam, RGEO:66); pl. pa.t. lantaner "fell" (pl.) (SD:246); lantier "they fell", a plural past tense of lanta- "fall" occurring in LR:47; read probably lantaner in LotR-style Quenya, as in SD:246. Also sg. lantië "fell" (LR:56); read likewise *lantanë? (The forms in -ier, -ië seem to be properly perfects.) Future tense lantuva, VT49:47. Participle lantala "falling" (with locative ending: lantalassë) in Markirya.
Quenya
lanta-
verb. to fall, to fall; [ᴱQ.] to drop
lanta-
fall
lanta
fall
lanta (1) noun "a fall" (DAT/DANT (TALÁT) ), also lantë.
lantar
fall
-r plural ending used on verbs with a plural subject (VT49:48, 50, 51), e.g. lantar "fall" in Namárië (with the plural subject lassi "leaves"), or unduláver as the pl. form of undulávë "licked down, covered" (PE17:72). The ending is sometimes missing where we might expect it; for instance, the verb tarnë "stood" has multiple subjects and yet does not appear as *tarner in PE17:71.
lanta-mindon
fallen-towers
lanta-mindon Qenya pl. noun "fallen-towers"; inflected compound lanta-ránar "in falling-moon" (with pre-classical locative -r) (MC:214; these forms are "Qenya")
lantë
noun. fall
A noun for “fall” appearing as an element of the title Noldolantë “Fall of the Noldor” (S/87).
Neo-Quenya: The word lasse-lanta “leaf-fall” (LotR/1107) indicates the noun for “a fall” should be lanta, which is also how the noun appears in The Etymologies of the 1930s (Ety/DAT). However, there is an alternate form lassewinta “leaf fall” in drafts of the Lord of the Rings appendices (PM/376) where the second element seems to be the infinitive of the verb winta-, so perhaps lasselanta also includes the infinitive of the verb lanta- “to fall”.
The form lantë more strongly resembles other Quenya nouns, which more often end in -e rather than -a. As such, I prefer lantë over lanta as the independent noun for “a fall”.
lantë
fall
#lantë (1) noun "fall" in Noldolantë, q.v. Also lanta.
isilmë lantalassë
in the moon falling
The ninteenth line of the Markirya poem (MC/222). The first word is isilmë “moonlight” followed by the active-participle (“-ing”) of the verb lanta- “to fall” with the locative suffix -ssë (“in”), which modifies the entire phrase, as suggested by Helge Fauskanger (AL/Markirya).
Decomposition: Broken into its constituent elements, this phrase would be:
> isilmë lanta-la-ssë = “✱moonlight fall-ing-in”
lasselanta
leaf-fall = autumn
lasselanta noun "leaf-fall = Autumn" (DAT/DANT, LAS1, Narqelion, LT1:254; "lasse-lanta" in VT45:24, but again lasselanta in VT45:26)
lasselanta
noun. (late) autumn, (lit.) leaf-fall, (late) autumn, (lit.) leaf-fall; [ᴹQ.] October
(taure)lanta
noun. clearing, open space in the forest
The Quenya verb for “to fall”, dating all the way back to the Qenya Lexicon of the 1910s, though in that document it had the form ᴱQ. lant- and the additional gloss “drop” (QL/51). In the Qenya Lexicon it was derived from the early root ᴱ√LANTAN [LṆTṆ], but in The Etymologies of the 1930s Tolkien changed the root {ᴹ√LANTA >>} ᴹ√DA(N)T “fall down” as the basis for ᴹQ. lanta- “to fall” (Ety/DAT; EtyAC/LANTA). Q. lanta- “fall” appeared regularly in Tolkien’s later writings as well (MC/222; PE17/62; VT49/47), most notably in the Namárië poem in its first phrase: ai! laurië lantar lassi súrinen “ah! like gold fall the leaves in the wind” (LotR/377).
The word lanta was occasionally used as a noun for “a fall”; see that entry for discussion.
Neo-Quenya: In Tolkien’s later writings, lanta- was used only for intransitive “fall”. However, we have no Quenya verbs for transitive “drop” other than 1910s ᴱQ. lant-, so I would assume that lanta- can be used this way as well for purposes of Neo-Quenya (QL/51). For example, lantan “I fall” vs. lantan i macil “I drop [make fall] the sword”.
