Many people's given names have meanings, some of which go back centuries. The specific meaning of your name varies depending on the name and the language it comes from.
By checking websites that offer information about specific names, you can find out the meaning of your own name. For example, the name "Ethel" comes from English and dates back to the 1800s. It is a short form of several names that have the Old English word for "noble" as their root. In the 1800s, the British began to revive a number of names from Old English, and Ethel was among them. It appears in William Makepeace Thackeray's novel "The Newcomes," which came out in 1855. You can find your own name by looking on a similar website.
