Name Teaser: Add-a-Letter
Lots of names can morph into variants just by adding a letter to the end. Sometimes the extra letter changes the sex: Robert expands to Roberta, Julia to Julian. Sometimes the letter changes the ethnicity, turning Carl into the Italian Carlo, then Carlo into the Spanish Carlos. You can make diminutives with a single letter, too -- just ask Mikey.
But when you add a consonant other than n or s, funny things happen. If you manage to make a new name at all, it's likely to be completely unrelated to the name you started with.
Here's an example from the top of the alphabet. Ada is a name that goes back about 250 years and is believed to come from the Germanic name element adal ("noble"). Add an m, though, and you have the Biblical Hebrew name Adam.
