With the overwhelming “Anglocentric” or “alphabetocentric” science of reading, the current review aimed to add to the science of reading acquisition from the perspective of abugidic writing system, distinct from the well‐research alphabetic writing system in multiple dimensions of orthographic complexity, as proposed by Daniels and Share (2018), such as linguistic distance, spatial arrangement and non‐linearity, and omission of phonological elements. Abugidic writing system is featured with scripts where each base consonant symbol denotes a consonant with an inherent vowel (/a/) and has billions of users in south Asia (e.g., India, Nepal, Sri Lanka), southeast Asia (e.g., Thailand, Laos, Cambodia), east Asia (parts of China) and Africa (Ethiopia and Eritrea). The current review describes the orthographic feature of Indic (Brahmi‐derived) and Ethiopic (Ge‘ez) scripts within the abugidic writing system and synthesizes existing findings on the literacy acquisition patterns specific to each script. Further, we elaborate on the multilingual and biscriptal language and literacy environment featured with the abugida‐writing societies and discuss the theoretical implication for considering multilingualism and biscriptality as an inseparable sociolinguistic factor when understanding the literacy acquisition of the abugidic writing system in particular and literacy in general.
