What is Sheng? The History and Meaning of Kenya's Urban Language

Updated 2026-01-01, 6 min read

Sheng is a constantly evolving urban language that emerged from the streets of Nairobi. It blends Swahili, English and dozens of Kenyan mother tongues into something entirely new.

Where Sheng came from

Sheng began in the low-income estates of Eastlands, Nairobi, as a code language for the youth. Over time it spread through music, pop culture, matatus and social media to become a national phenomenon.

How Sheng is built

Sheng borrows freely. A single sentence can mix Swahili grammar, English words and terms borrowed from Kikuyu, Luo, Kamba, Luhya and other Kenyan languages. New words are invented constantly, which is why a dictionary like this one matters.

Why Sheng matters

Sheng is more than slang — it is a symbol of urban Kenyan identity. It appears in music (gengetone and hip-hop), advertising, politics and everyday conversation. Learning Sheng is a way to connect with modern Kenyan culture.
