The Kalenjin are a Nilotic people living in Kenya. They speak Kalenjin language which is spoken in dialects specific to individual contingent tribes and/or sub-tribes. The system observes that every name of a person, object or place has a meaning. The system has been subject to westernization and attrition to linguistics due to the Kenyan adoption of Swahili language as a lingua-franca and the dynamic view that indigenous languages are provincial and irrelevant.

The first name of the Kipsigis males is prefixed by the term <nowiki/>'Kip and then added a suffix descriptive of the prenatal, natal or post-natal places or time or weather and situations. It was to be widely used before initiation and rarely after, only as the mother mourns a dead soldier son or during divorce. <br />
After males were initiated at about their late teenage and early adulthood, they would come out as having achieved citizenship of the Kipsigis jurisdiction and would be accorded a patronymic surname derived from the first name of the father. For instance, if the father is named Kiptoo, his son after being initiated is accorded the name Araap Too.
