Em Origin and Meaning

The name Em is a girl's name meaning "universal or rival".

There are a lot of little girls called Em today, but not that many named Em, just Em. As a first name, it's a bit reductive, especially with all the children named Emma, Emily, Emilia, Emeline, and onward. But we can see it working as a creative middle name, perhaps a clever way to honor Grandpa Mike?
