Zehn is a male first name.
Recently, the name Zehn has been given only a handful of times a year and is therefore particularly rare, at least in the US. In recent years, not even one boy in 100,000 has been named Zehn. That means that a boy named Zehn is exceptional and may not meet another person with the same name his whole life.
If your name is Zehn and someone asks after your name, you can of course just tell them what it is. But sometimes that isn't so easy - what if it's too loud, and you don't understand them well?

Elephant
Hat
Nut
