Kiswahili language has undergone a lot of changes in the last decades especially at the lexical level. Many lexical items have been coined, adapted, borrowed or modified to express concepts that were hitherto unknown or non existent in the Swahili world view cosmology. One area that has witnessed a lot of these changes has been the area of sciences, or better put science has been a prime causer of many neologisms in this language. This eventuality has gone a long way to disprove the naive assumptions that the language has not come of age to express scientific concepts.
