el kata refers to a famous Dominican urban merengue artist, also known as a mambero, from the town of La Cienaga in Barahona (a province in the southwestern Dominican Republic). While the term technically comes from a Greek preposition meaning according to or down from, in local context it is used as the stage name for this performer, known for hits like Loca con su tiguere.
It cannot be used in Spanish with the same sense as the Greek preposition, we can only use el kata as a subject.
