The paper is an exploration of time referencing terms in Ndebele. The main thrust is on the nature of time referencing terms. Time on mastics in Ndebele is based upon the speakers’ cognition. The speakers’ experience and interaction with the world are of significant influence in the creation of meaning in Language particularly in the meaning of time naming terms. Time on mastics in Ndebele and in most African societies depend on speakers’ Indigenous knowledge systems. Indigenous knowledge systems of a people are embedded in their language. It is impossible to detach them from the speakers’ language. Their language will always reflect their experiences, thoughts, beliefs, culture and life in general. This paper establishes the idea that language is a product of the speakers’ observation and perception of the world.
