ඈ, n. The fourth vowel of the alphabet, the lengthened sound of ඇ. Its non-initial form is (ැ) following the consonant it vocalizes, as මෑ Mã.

ඊ, n. The sixth vowel of the alphabet. Its sound is the previous vowel lengthened, and is the same as ee in Peel or Feel. Its non-initial form is ී placed above the consonant it vocalizes, as කී, මී, kí, mí.

ඒ, n. The twelfth letter of the alphabet. Its sound is that of the preceding vowel lengthened: as a in Fade, but somewhat broader, the initial sound of it being maintained throughout, without changing into i as the English sound does: consequently in English words it would seem somewhat inelegant. Its non-initial form is the same as the preceding, but lengthened by the addition of /?/ or ි to the consonant, as කේ ké (cay), මේ mé (may).
