The Quenya name of S. Mablung, a compound of lungo “heavy” and má “hand” (VT47/19). Normally long final vowels were shortened in Quenya, so perhaps its proper form would be Lunguma, as it appeared in some notes from the early 1930s (PE21/41).

Conceptual Development: The first appearance of a Quenya cognate for Mablung was ᴹQ. Lunguma in notes from the 1930s. It reappeared in notes from the late 1960s with long á (VT47/19). In these same notes, this name also appeared in the form Lungumaqua where its second element was the direct equivalent of S. mâb “hand” (VT47/19), a form that also appeared in notes on Sindarin mutations from the same period (PE23/144). However, Q. maqua was elsewhere used as an alternate word for “five” (lit. “hand-full”), much as English “dozen” is an alternate word for “twelve” (VT47/7), so the variant Lungumaqua may be an archaic form of this name.
