Cleat is an uncommon given name of uncertain origin, but it may have been derived from the Scottish surname Cleghorn, which means "clay hill" or "clear hill." The name Cleat has gained some popularity as a unisex given name in recent years, possibly due to its unique sound and association with strong, sturdy objects like cleats used in sports. However, it remains relatively rare compared to other names.
In 1921 alone, there were five babies named Cleat born.
