A lectern is a stand with a slanted top used to hold a text at the proper height for a standing lecturer. Lecterns are mostly used in an academic or religious context, but can also be used for political speeches or for musical performances.
Some forms of desks resemble lecterns because of their slanted top.
Lecterns and spanking
A strong-built lectern or desk with a slanted top can be used to lay a spankee over - typically found in school spanking or in religious institutions. There are two ways to do this: either with their buttocks at the low side of the top and their head at the high side, standing (similar to the position at a birching pony), or with their buttocks at the high side of the top and their head at the low side. In the latter variant, the spankee's buttocks are in a more prominent position for spanking (bent-over-object position), however their feet are usually off the ground and dangling in the air, so that this position is more uncomfortable, as the spankee's full weight rests on their abdomens.
Depending on the height of the lectern or desk, an adult spankee may be able to keep standing even when bending over from the higher side.
