The importance and effects of colonization and globalization cut across nations. Language is seen as a medium of
developing communication across cultures and nations. We examine the impact of colonization on language shift,
language endangerment, language extinction and linguicide on languages in the Americas and Africa with reference to
Ghanaian languages. The paper looks at the effect of European hegemony on other languages and the areas that are
much affected like indigenous languages, culture, religion, education, and the economy. It further miens at methods
that should be used to create the awareness of linguicide through linguistic decolonization, language maintenance, and
revitalization. It concludes that despite attempts to use the electronic medium for information sharing in local African
languages, these have been corrupted by the imperialist languages such as French, English, and Portuguese.
