Make sure the name you want to translate into Italian has its origins in Latin, ancient Greek, or Christianity. You will not find an Italian translation of a modern American name like "Chelsea" or "Wendy."
Visit a reputable website that translates names into Italian. For instance, websites such as Behindthename, Dadezzio or iGoogle allow you to translate a name into Italian at no cost. Also, Behindthename for example, will give you the medieval, masculine, feminine, or other forms of your name in addition to the Italian translation. So, if you are translating "Christian" and you want the diminutive form, the result will be "Cristiano" or "Tina" for the feminine version. Most Italian diminutive forms include male versions such as -ino, -itto, -ello, -iano, which feminine versions are -ella, -etta, and -ina.
Enter the name you want to translate in the search box. Depending on the website you are using, you generally must choose "Italian" from the drop down language list. A site like Dadezzio is only dedicated to translating American names into Italian.
Choose a form in which to translate your name if this option is available. Those forms include, gender, variant, short, diminutive, Latinized, and more. Then select "Search," and it will take a few seconds to come up with the Italian translation of your name. For example, you can enter "Hilary," choose the feminine form of the name and the result will be "Ilaria" or "Ilario" if you change to the masculine form. Most Italian male names have their feminine form and they usually use an "a" ending for a feminine version compared to an "o" ending for the masculine form. The Latin "us" ending is generally substituted for the masculine "o." For instance, the Latin name "Claudius" becomes "Claudio" in Italian, which is "Claude" in English.
