@Careful.
Almost every Cameroon citizen speaks French, or English. So I don’t think the other languages have much to do with it.
” French and English are the official languages of Cameroon. Eight out of the ten regions of the nation, housing 83% of the population of Cameroon, are francophones. The remaining two regions, representing 17% of Cameroon’s population are mainly anglophones. However, the proportion of anglophones in the country is gradually decreasing.”
