This question already has an answer here:
Note: I'm not looking for namesake.
I heard a friend use such a word in the context of the following sentence, and now I've forgotten it:
"Anna and my sister [Anna] may not have much in common, but they are [word]"
I am a hundred percent sure that the word wasn't namesakes, but I think it might have started with an n as well. I tried some reverse dictionaries, but couldn't find anything, so I turned here for help.
Are there any other single words to describe the situation of sharing someone's name (when not named after that person; or in a coincidental manner)? Thanks.
