 "Ómatehtar" modes can vary in that the vowel stroke can be placed either on top of the consonant preceding it, as in Quenya, or on the consonant following, as in Sindarin, English, and the notorious Black Speech inscription on the One Ring.The other main difference is in the fourth "tyellë" below, where those letters with raised stems and doubled bows can be either voiced fricatives, as in Sindarin (general mode at right), or nasalized stops, as in Quenya (classical mode).In the "full writing" modes, the consonants and the vowels are represented by Tengwar.
