MIXLATTO
The words Mulatto and Mixlatto are often interchangeable because two Mulattos ALWAYS produce another Mulatto.
HOWEVER, a CHILD of two mulattos can also be correctly called a "Mixlatto", making those words indisputably synonymous.
OTOH, (On the other hand) and technically-speaking, ...a child who has one Caucasian (white) parent is ALWAYS a "Mulatto".
But, for those very few people whom have reportedly found the MUL prefix of "Mulatto" to be both, "derogatory, offensive & "dehumanizing", ... the use of MIXLATTO may be found to be much more agreeable to them.
