twinning

Being someone's double

Twinning describes the process of pairing or matching—cities that twin become "sister cities," sharing cultural exchanges.

In crystallography, twinning occurs when crystals grow together in mirror-image formations.

In internet slang, twinning celebrates when two people match unintentionally: We showed up in the same outfit—twinning!

The word often carries delight at coincidence or connection.
