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 the aforementioned notes from the 1930s. It reappeared in notes from the 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”. 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.
