<translate> Ili kuhakikisha uenezaji wa Kiswahili Sanifu, Kamati ya Kimaeneo ya Lugha Kiswahili iliyoundwa na Wazungu pekee, iliidhinisha vitabu vya kufundishia lugha hiyo shuleni. Vitabu vya kiada viliandikwa na kuhakikiwa na Wazungu na kupitia hili, msamiati ulibadilika na baadhi ya maneno kufupishwa na maana yake kubadilika kabisa. Kwa hivyo, kadri lugha hii ilivyosanifishwa, ndivyo ilivyozidi kuyumba kutoka kile wazungumzaji asilia wa Kiswahili walichokijua kama Kiunguja. Wengine wanaona usanifishaji kama chombo, kwa mara nyingine tena kwa mkoloni, kuangamiza lahaja zingine. Matumizi yake na uenezaji uliokokotolewa shuleni ulisababisha kupungua kwa matumizi ya lahaja nyingine zinazohusiana na hali inayojulikana kama Ukosefu wa Usalama kwa Lugha.

To ensure the propagation of Kiswahili Sanifu, the Inter-territorial Language Kiswahili Committee, made up entirely of Europeans, would approve textbooks used to teach the language in schools. Textbooks were written and reviewed by Europeans and through this, vocabulary changed with some words being shortened and their meaning completely changing. Therefore, the more this language was standardised, the further it drifted away from what native Kiswahili speakers knew as Kiunguja. Some see the standardisation as a tool, once again for the coloniser, to massacre other dialects. Its use and calculated propagation in schools resulted in the reduced use of other related dialects and in a phenomenon known as Linguistic Insecurity. Write authors Wilma Bucci and Milton Baxter:
