[Deletia]

Re-learned a forgotten word today while rereading "Microserfs" by Douglas Coupland: Deletia.

When you reply to an email and remove the bulk of the original message, apparently you should (or at least can) replace the deleted text with "deletia" in brackets. Maybe I'll start saying this word when I respond to people in conversation. ...Signify that their words have just passed through me and are gone. Their part of the conversation is just [deletia]. Like whatever I say in response.

In the Coupland's words, "it stands for everything that's been lost."
