Dholuo and the Luo Lakeside Script

Nilotic languages in Kenya and East Africa

The Luo of Kenya are a Nilotic ethnic group and the fourth-largest community in Kenya (about 10.6%, or over 5 million people), primarily residing in the Lake Victoria basin of Western Kenya.

Origins

Between 2009 and 2012, Kefa Ombewa and Paul Sidandi created the Luo Lakeside Script to write Luo languages. Written left to right, it captures the tonal structure of Dholuo more accurately than the Latin alphabet.

Unicode

Digitization of the Luo Lakeside Script is imminent, with implementation of an accepted Unicode proposal anticipated in 2027.

Try it yourself

The number one thing we can do to preserve scripts is actively use them. Until Unicode adoption, anyone curious to try the script can use the keyboard available through Keyman. If you care about projects like this and want to see languages like Dholuo represented on the web, in media, or in AI systems, consider reaching out.

Ditema Tsa Dinoko

Southern Bantu languages in South Africa and Lesotho, also known as isiBheqe soHlamvu

A script for the Southern Bantu language family, including isiZulu, isiXhosa, Sesotho, Setswana, and many other languages. Developed collaboratively between 2010 and 2016 by a network of South African linguists.

One of the boldest projects in modern linguistics

Ditema Tsa Dinoko was created by a collaborative network of South African linguists over six years. It emerged from collective effort, which is fitting for a writing system meant to serve an entire family of languages and cultures.

Syllabic structure

The script draws structural inspiration from Asian syllabic systems, particularly Hangul and Hiragana, adapting their logic of composing syllable blocks to fit the phonological patterns of Southern Bantu languages.

Wall painting

The visual character of the script is rooted in the decorative geometric wall painting traditions historically practiced by Basotho women in Lesotho and South Africa.

Symbol and bead

Further influence comes from the amabheqe beaded love messages of the Zulu people and the ukugwala murals of the Ndebele.
