The socio-economic-cultural pressures inevitably imposed upon the initial Christian community of Tamontaka must have been the very environment which was responsible for the formation of a creolized language in the place.
That Zm had its role in the later development of Ct cannot be denied, but the Ct had its own separate point of incipience and growth is another fact.
The Ct language situation was further affected by the phenomenal population increase which was occasioned by the migration of homeseekers and settlers to the Province of Cotabato. This was brought about by the opening up of vast public lands which were converted into homesteads. Public highways and bridges were constructed and evidence of material progress drew more people from the different parts of the country.
Cotabato, otherwise known in the Philippines as the 'empire province', was thronged by homeseekers, agricultural pioneers, capitalists, and pioneering professionals. Later still, the American missionaries, the Oblates of Mary Immaculate, took over the spiritual guidance and Christian education of the province. They contributed significantly to the cultural expansion of the province through schools, hospitals, press and radio. The waves of population invasion have likewise brought about a linguistic invasion into the language situation of Ct native speakers.
