Abugida
An abugida ( ; from Geʽez: አቡጊዳ, 'äbugīda)—sometimes also called an alphasyllabary, neosyllabary, or pseudo-alphabet—is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, like a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional.
