A place where animals are killed for their meat.
The abattoir was busy processing livestock for the market.
Abattoir comes from the French word 'abattre' (meaning to slaughter) combined with the suffix '-oir' (indicating a place). Thus, an abattoir is a place where animals are slaughtered for food.
Imagine a place where animals are 'slaughtered' ('abattre') — that's what an abattoir is, a location specifically for this purpose.
