The sixteenth line of the Markirya poem (MC/222). The first word is the plural of the adjective ninquë “white” modifying the plural of the noun carca “rock”, followed by the infinitive (or short active-participle) of the verb yarra- “to snarl”, used adjectivally. Note that carca normally means “fang, tooth”, so its uses for “rocks” here may be poetic to describe sharp rocks, as suggested by Helge Fauskanger (AL/Markirya).
Decomposition: Broken into its constituent elements, this phrase would be:
> ninqu-i carca-r yarra = “✱white-(plural) rock-(plural) snarling”
Conceptual Development: In the first draft, noun was the plural of ondo “rock” (MC/222).
ninquë adj. "white, chill, cold, palid" (WJ:417, SA:nim, PE17:168, NIK-W - spelt "ninqe" in Etym and in LT1:266, MC:213, MC:220, GL:60), pl. ninqui in Markirya. Compounded in Ninquelótë noun "White-Flower" (SA:nim), = Sindarin Nimloth, the White Tree of Númenor; ninqueruvissë ("q") "white-horse-on" _(MC:216; this is "Qenya", read _ninqueroccossë or *ninquiroccossë in LotR-style Quenya). Normally ninquë would be expected to have the stem-form ninqui-, given the primitive form ¤ninkwi; Ninquelótë rather than *Ninquilótë must be seen as an analogical form.
