When a vowel is to be pronounced clear and open the following consonant will be doubled: (Tanna, Mekka, Bonny). To lengthen a vowel sound, it will not be doubled, but if the vowel is repeated each will be pronounced separately (Nuuluha, Oosima).
But one accent (') will be used to indicate if particularly necessary, that is, in exceptional cases, the syllable on which stress is to be laid (Matupí).
