Pirayas

Part of speech: noun

Definitions

1. A type of carnivorous freshwater fish known for its sharp teeth and aggressive behavior, often found in groups
2. A species belonging to the family Characidae, commonly inhabiting rivers in South America
3. Popularly recognized for their feeding frenzies, especially when they sense blood in the water

Etymology: The name comes from Tupi, the language of indigenous peoples of the Brazilian Amazon region. It combines "pirá," meaning fish, with a word for tooth, so the literal sense is "fish-tooth." Portuguese speakers adopted it as "piranha," and European naturalists carried it into English and other languages. The spelling "piraya," with its plural "pirayas," is a variant that follows Spanish and other transliterations of the same Tupi-derived name. The fish's reputation for frenzied attacks is much older than the name's spread, but the English word itself carries no sense of blood or frenzy. Those associations come from the fish's sharp, triangular teeth and from accounts of its behavior, which travelers and naturalists reported with growing drama in the 19th and 20th centuries.
