What means
It represents /e/, not the English name “ee.”
Ol Onal writes every vowel as a full letter, instead of attaching a vowel mark to a consonant. The slashes label a speech sound.
How was Ol Onal accepted as a Bhumij script?
A Bhumij community organization chose it in a 1992 contest.
Mahendra Nath Sardar developed Ol Onal between 1981 and 1992. Adim Bhumij Samaj, a Bhumij community organization, chose it in a contest among three script proposals. Bhumij is also written with other alphabets, including Devanagari, Bengali, Odia and Latin.
