Filly is a generic term for a female horse. It is only applicable for females, so when you hear it, you won’t have to wonder about the horse’s gender. However, filly is only applicable for female horses up to the age of three.

When a horse is born, it is a foal. Foal applies to all baby horses up to the age of one, whether it is female or male. If the foal is a female, you can also call it a filly. If you hear the word filly, you will know that horse is age three or younger.

Another term you might hear is filly foal. If you hear filly foal, the horse is under the age of one. The word filly is the same whether the equine in question is a pony, horse, or miniature.

What Is A Male Foal

If the foal is a male, it is a colt. Colt is only applicable if the foal is male. Like filly, colt applies until the horse turns four. However, if you castrate a colt, it is then a gelding.

What Is An Older Female Horse

When a female horse turns four, it is no longer a filly. The correct term to use is now mare. All-female horses are mares, and the word is never used to describe a male. You might hear the word broodmare.

This word describes a certain type of female horse. A broodmare is a female horse that does not compete but has a career inbreeding. Many high-quality mares retire from racing or competition to become broodmares.

Broodmare brings us to another female horse term, dam. Dam refers to the mother of a horse. For example, someone might say who is the dam of your horse?

They are asking who is the mother of your horse. Grand dam refers to a horse’s grandmother. When making breeding decisions and looking at pedigrees, the dam and grand dam are important.

Origin Of The Word Filly

The origins of the word filly are not exactly clear, but it is likely that it came into existence around the start of the 15th century. There are two possibilities for the English version. One is that it comes from the Old Norse word for a female foal, fylja.

Another possibility is the Proto-Germanic word fuljo. The spelling of filly originally was fyly or filli.
