Pigs have three main collective nouns: drift, drove, and sounder. Other collective nouns for a group of pigs include fleet, herd, trip, team, flock, singular, passel, and parcel. A litter or farrow is used to refer to a group of young pigs, while a sounder or singular is used to refer to a group of wild pigs. A parcel or passel is used to refer to a group of heavy pigs weighing more than 54 kg.
The collective nouns drift and drove are derived from the Old English word drifan, which means to drive or push. This term was used to describe the act of driving a herd of pigs from one place to another. The term is still used today to refer to a group of pigs being driven or herded together.
