Harma
From Tolkien Gateway
harma is a noun meaning "treasure" in Quenya.
Etymology
PQ *kharmâ from Root KHAR. In the First Age it was pronounced charma.
Tengwar
Charma was the original name of the eleventh letter of the Tengwar alphabet and had the value of "ch".
Over time Quenya lost the "ch" sound in the beginning of words, which became soft h and was written with Halla or Hyarmen; the letter itself was renamed acha and was now used only medially.
