Some people have origin stories. Pardis Mahdavi has a hyphenation story. Her Iranian family was the target of a hate crime in Minnesota. She was stripped of her citizenship in Iran. Eventually she embraced the hyphen between the words 'Iranian' and 'American' as her identity: two cultures within one person.

But what exactly is the function of a hyphen? Does it unite two ideas, or divide them? Together with Pardis Mahdavi, we trace the many disputes surrounding this seemingly humble horizontal line, from Romans and Celts, then via Hollywood to politicians and lexicographers.
