A word appearing as ᴱN. pant “money” in the Early Noldorin Grammar of the 1920s (PE13/124), possibly related to the early root ᴱ√PANA “arrange” (QL/72). Tolkien indicated this noun was inherently plural.
Neo-Sindarin: Since √PAN “arrange” survived in Tolkien’s later writings, I would retain ᴺS. pant “money”, perhaps originally referring to a method for arranging the exchange of goods.
