The short story
Acosta is a Spanish and Portuguese habitational surname associated with costa, “coast,” “shore,” or “slope.” It could identify someone who lived near a coast or on a hillside, or someone who came from a locality with Costa in its name. Da Costa and Dacosta preserve related Portuguese and Spanish forms, while Costa is a broader cognate rather than proof of one family connection. The landscape word is clear, but different regions produced separate Acosta lines. Place is the best catalog type, with likely confidence because the geographic clue is stronger than any single proposed ancestral locality.
