Etymology: "Characids" is the plural of "characid", a member of the family Characidae, a large group of mostly tropical freshwater fish that includes tetras and piranhas. The singular "characid" is formed from the genus name "Characinus", which in turn is built from Greek roots, with the family name taking the standard zoological ending "-idae" (for family) and the English form adding "-id" for a member of that family. Because the taxonomy is what gives the word its shape, the plural simply follows regular English practice: a group of characids is "characids," the same way "cichlids" names members of the cichlid family.

Synonyms: characin fishes, characiform fishes
