A baby horse is called a foal. The word “foal” derives from the Old English word meaning “young animal”.
The reason they are called this is because of their size and appearance. Foals are younger animals, so looking specifically at equines, the name “foal” refers to all breeds under one (or two) years of age regardless of sex since equine foals does not have any visible sexual features until after their first birthday. In other words, while some people use the term “filly” or “colt” for an individual horse that has not yet attained full growth; others use these terms interchangeably with “foal” or “infant horse” because in general, a young foal is about the same height and weight as a young pony under two years of age.
Baby horses are called foals. Foal is a loan word from the Old Norse words ‘fylja’ and ‘fól’, meaning ‘mare’s offspring.’
In horse breeding, the pregnant mare is sometimes referred to as “the dam”. The plural word for this usage is “dams”. Thus, a group of more than one breed of horse can be collectively referred to as “a herd”, or, if all female horses together in a group, they can be known as “a string” or (collectively) an equine harem.
A baby horse is called a foal.The word “foal” (which comes from the Old English words ‘fol’ meaning foliage and referring to little leaves) literally means ‘young, tender branches of a plant’. Which in turn aptly describes how young horses are at first – all soft and green.
Origin of the word “colt” is from Middle English colt, possibly an alteration of Old Norse kolt meaning “young male horse.”
A colt is a young male horse. When people speak about a newborn colts, they’re talking about what we call a baby horses. A juvenile horse penis will not descend until he’s four or five years old and until then he will be known as a colt. This is also why it’s called vernalization – this term refers to the rejuvenating effects that seasonal change like winter have on the reproductive system for animals that live in temperate climates.
A baby horse is called a foal. Now, it’s not clear why they’re called that. There are a lot of legends about the origins of the name “foal.” One story suggests that they were named after the valley in which they first appeared- in old English, fairy valley was spelled ‘fael.’ Another legend says that because horses have long noses and humans have round nose peeking out through a smiling mouth, the human looks like he or she has blond hair (or fair) all around their mouth area–thus looking like a halo (a safeguard against accidents). So for some people, as there is no definite answer to this question… some people think from where these animals come from then maybe it is a good enough explanation why they were called foal.
