pi·co de gal·lo (pēkō də gäyō)
A relish made of raw, chopped tomatoes, onions, hot chili peppers, and cilantro with lime juice, used in Latin American cuisine.
[American Spanish, from Spanish, rooster's beak (perhaps from the resemblance of the chopping of the ingredients to the pecking of a rooster as it breaks food into pieces) : pico, beak; see PICO- + de, of (from Latin dē, from, off; see DE—) + gallo, rooster (from Latin gallus; see gal- in the Appendix of Indo-European roots).]
