Tyellë

Tyeller (singular tyellë) is the Quenya word for "Grade".

In the Tengwar system of writing, the Tyeller were the six "grades" used to indicate modifications to a basic sound in Tengwar and represented eight modes of articulation in the mouth.

The Tyeller were signified by the length of the telco and the number of the luvar (one or two).

For example, where the first tyellë referred to the basic patakar, the tengwar known as Tinco, Parma, Calma and Quesse, the following tyeller would typically represent modifications of their basic sounds.

Specifically, in the sequence known as tincotéma, the next tyeller would normally represent the dental sounds like nd, d, th, dh etc, according to the system.

Etymology

tyelle obviously derives from PQ *tjellê, from a possible root *TJEL

It is also one of the few words ending in -e which forms the plural in -r, instead of -i, hence tyeller instead of **tyelli
