This word began from the Latin word "radix" meaning root and referring to literal plant roots.  This was later the basis for the Old French word "desraciner" meaning to dig out or pull up by the roots, but unfortunately it took up other meanings when the word was absorbed into English.  The most horrific example of the meaning of this word happened in the mid 17th to early 20th centuries when it became the foundation for the American Indian Schools.  In this example, young Native Americans were plucked from their families and tribes and forced to live in "residential schools" in order to civilize or assimilate them into the Euro-American culture.  The Native Americans were forced to change their style of dress and appearance, forced to stop using their native tongue and start using English instead, and assume a totally new and different way of life.  

Native Americans were deracinated by the U.S. and Canadian governments in an attempt to '"civilize" them.  

I want to deracinate the fire ants from my yard.
