Pato is a word commonly used in Spanish to refer to a duck, but it also has several synonyms that can be used in different contexts. Some of the synonyms for pato in Spanish include anade, ave acuática, palmípedo, and ánade real. Anade is a Spanish term used for all wild ducks, while ave acuática refers to aquatic birds that live in freshwater environments. Palmípedo is a more technical term frequently employed in the scientific community, which refers exclusively to web-footed birds. Ánade real, on the other hand, is used to describe the most common species of duck found in Spain, as well as a variety of other countries.
