Etymology
the word 'oubliette' is a direct borrowing from french, where it literally means 'a place for forgetting'. it is built from the old french verb 'oublier' (to forget), which itself descends from the latin verb 'oblivisci'. the diminutive suffix '-ette' implies a small or specialized place. thus, the term's grim logic is transparent: it denotes a small, concealed dungeon designed for a prisoner to be forgotten, a meaning that has remained unchanged since its adoption into english in the late 18th century.
