A quick search in the dictionary will result in the definition of Latina/o and Latinx yet Afro-Latina/o/x is not defined or even suggested. 

Including the term "Afro-Latina" in the dictionary is about creating visibility for those who have been erased from media for far too long. The term is to acknowledge someones Blackness as a product of being of Latin-American descent. For many of us, using the terms Afro-Latina/o/x rather than simply Latina/o/x allows us to center our Blackness and not negate it.
