Leb Lango is spoken by millions of Lango people who are geographically located in central Uganda, and politically located in northern Uganda. It can be traced back to, the languages spoken by their, Ateker and Galla/Oromo ancestors of Ethiopia during, BCE and Medieval Era before they finally arrived at Otuke Hills (Got Otuke) in Uganda. The language has since absorbed vocabulary from a huge number of sources which has seen a significant change to its orthography, grammar, and pronunciation. Currently, the language consists of a blend of many sources and what was originally leb lango. Most of the vocabulary in this dictionary is based on the modern day lango language which was compiled between 18th, 19th, 20th and 21st Century.
