n.    A woman of mixed racial ancestry, especially of mixed European and Native American ancestry.

[Spanish, feminine of mestizo; see mestizo.]

During the colonial period of the Philippines, the term "Mestizo" originally referred only to those of mixed Filipino and Spanish or Mexican ancestry. However, the term soon became generic and synonymous for "mixed race" and has been used to refer to all Filipinos of physically traceable mixed ancestry. *from thefreedictionary and wikipilipinas*
