>>>Hi everybody,

>>>What word do we use for the people having the exact same last and first name (different people)?

>>"Namesake" is one that has the same name. I believe this refers to the first name, and I don't think there is a special word for the combination.

>I don't think "Namesake" quite fits Naomi's definition. A person's namesake is somebody after whom s/he has been named. In my mind, it implies a deliberate intention to match names and most frequently matches first,middle name with first.last name.

>AFAIK, there isn't a word. There is, however, a phrase. "People who have the same first and last names"

Snappy! ;-)
