Which Latin word refers to a 'stool'?

The word 'sella' is the Latin term that specifically translates to 'stool' or 'seat'. In various contexts, 'sella' can refer to different types of seats, including those that are lower to the ground, such as a stool. It's often used in literature and inscriptions to denote furniture designed for sitting, and it is associated with the idea of a simple or basic seat compared to more elaborate forms of seating.

The other options relate to seating but do not translate directly to 'stool'. 'Sedes' primarily means 'seat' in a broader sense and can refer to a position of authority or a place where someone sits, while 'mensae' translates to 'table', emphasizing a place where items are laid out rather than a seat. 'Atrio' refers to a large open space or atrium in a house, which does not pertain to seating. Therefore, 'sella' is the most accurate choice when specifically seeking a word that means 'stool'.
