bestiality

Synonym discussion
Sense: noun/2
All four words describe extreme cruelty, but they pick out different shades. 'Brutality' is the most neutral and the most common: it focuses on rough physical violence, as in 'police brutality'. 'Savagery' adds a sense of wildness and loss of control, often used for attacks or warfare. 'Barbarity' stresses how uncivilised an act is, and is the standard word for atrocities reported in news and history books. 'Bestiality' is the strongest and rarest of the four; it suggests the person has sunk below the human level and is acting like a beast. Use 'brutality' for everyday news ('the brutality of the assault'), 'barbarity' for war crimes, and reserve 'bestiality' for literary or moral writing where the writer wants to shock the reader.

Etymology
Borrowed into late Middle English from Old French 'bestialité', built on Latin 'bestialis' ('like a beast') and 'bestia' ('animal, beast'). The original meaning was simply 'the nature of a beast' — that is, the qualities that make an animal not a human. From the late 1500s, English writers stretched the word in two directions: a metaphorical sense for cruel or coarse human behaviour, and a literal sense for sexual contact between a person and an animal. Today the literal sense dominates in legal English, while the older metaphorical sense survives in formal and literary writing.
