mettanyëproper name. I End
Section title of a late version of the poem, “The Trees of Kortirion” (LT1/43). The initial element of the name seems to be metta “end”. Its final element may be the 1st person pronominal suffix -n(yë). If so, metta- here might be used as a verb and the full the word might mean “*I End”.
metta noun "end"; Ambar-metta "world-end, the end of the world" (EO); mettarë *"end-day" = New Years' Eve in the Númenórean calendar and the Steward's Reckoning, not belonging to any month (Appendix D). The word Mettanyë, heading the final part of the poem The Trees of Kortirion, would seem to be related (LT1:43)
