Several collective nouns describe a group of ponies, the most common being a string, a marmalade, and a herd. The word ‘string’ comes from the way ponies are often kept in small sets of three or four, so the whole little group ends up being called a string. The term ‘marmalade’ is said to have grown out of the sight of ponies grazing together in big numbers, all clustered into one mass. A herd, meanwhile, names a large gathering of ponies that can run into the hundreds.
