Explanation

If you ride your trusty steed to school, you're traveling on horseback. Your arrival is going to make your classmates wish they had their own ponies! When horseback is used as a noun, it means "the back of a horse." It's more commonly used to describe someone who sits on a horse's back, a horseback rider, or as an adverb to describe that mode of transportation. Even if you're not experienced with horses, you may dream of one day going horseback riding on a beautiful beach!
