In Meitei script (Meetei Mayek), the full sound carrying letters, formally known as "Mapi Mayek" (literally meaning "Mother letters" or "Master letters") play a very crucial role. All of these letters are consonants except 3 letters, which are ꯎ (U), ꯏ (E) and ꯑ (A).

Among the full sound carrying letters, there are two types:
 * 1) Principal full sound carrying letters
 * 2) Extended full sound carrying letters
