— Sir Walter Scott, “Wandering Willie’s Tale,” Selected Short Stories
What’s more, if you persist in disobeying me, I’ll have no choice but to delate you to His Excellency the Archbishop.

Delate stems from the Latin word dēlātus which is the past participle of dēferre meaning “to bring down,” like the modern English word defer.
