A word for a “drinking-vessel” appearing in the Quendi and Eldar essay from 1959-60 as a derivative of ✶julmā [yulmā] = √YUL + ✶-mā “✱thing for drinking” (WJ/416), where the final lm became lf (pronounced [lv]). It was cognate to Q. yulma, and hence probably also means “✱cup”.

A noun appearing as N. calf “water-vessel” in The Etymologies of the 1930s derived from the root ᴹ√KALPA of the same meaning (Ety/KALPA). The same word appeared in the Gnomish Lexicon of the 1910s, but had the form and gloss G. calph “bucket” (GL/25).
Neo-Sindarin: For purposes of Neo-Sindarin, I would use the spelling ᴺS. calph to make the pronunciation clear, as suggested in HSD (HSD), since final f is generally pronounced [v] in Sindarin. Given its generic gloss “water-vessel”, I would use this word for any larger vessel for holding or carrying water.
