Unque is also the name in Quenya of the sixteenth letter of the Tengwar alphabet. It is the fourth letter of the fourth grade or Tyellë, which contains "voiced spirants" and it is the fourth letter in the fourth series of consonants. In the standard spelling of Quenya this letter represents NKW (or transcribed in English as NQU) while in Sindarin this letter represents GHW. In Westron the fourth series is used for the k-series, the Calmatéma, and this letter represents GH. The Westron name for this letter is Agha.
