Wash One’s Dirty Linen in Public Idiom Origins
The term has its roots in European customs and the literal act of washing dirty clothing.
Google’s historical data project has found its first usage somewhere around the 1910s, as shown in the following graph:
Here’s an overview of its origin:
- Laundry Practices: In earlier times, washing clothes was a communal activity. Families would gather by rivers or communal washing areas to clean their garments. Dirty clothes, or “linen,” were a direct reflection of one’s household’s cleanliness and hygiene.
- Private Affairs: Washing one’s dirty clothing was considered a private affair, and it was seen as improper or embarrassing to air dirty or stained garments in a public setting where others could see. As such, the act of publicly displaying or discussing one’s “dirty linen” became synonymous with revealing private or sensitive matters to others.
In modern times, when someone is said to “wash their dirty linen in public,” it means they are openly discussing personal matters or disputes that might be better kept private.
