Frequently asked questions

Is sonder a real word?

It is a real word in the sense that people understand and use it, but it is an invented one with no history before the 2010s and it does not appear in most established dictionaries. Treat it as a useful coinage rather than standard vocabulary.

What is the difference between sonder and empathy?

Empathy is feeling with a particular person whose situation you can picture. Sonder is broader and more disorienting: it is the abstract shock of grasping that every anonymous person in a crowd has an interior life as detailed as yours.

How do you use sonder in a sentence?

It works as an uncountable noun for the feeling itself, as in 'a moment of sonder' or 'I felt sonder watching the airport crowds'. There is no established verb or adjective form.

What is the meaning of sonder?

"sonder" (noun) means the sudden realisation that every stranger you pass is living a life as full, detailed and complicated as your own.
