Any hook that you use to hang up wet clothes to air dry can be identified as a tenterhook, though this method is rarely used anymore.

Now that we have washing machines and dryers, the need for tenterhooks to hang wet clothes outside has been drastically reduced.

In the old days, clothes had to be dried by hanging them outside, and they were usually hung on wires with tenterhooks.

The best way to air dry wet clothes is to hang them outside on some sort of frame with a few tenterhooks.

A tenterhook is used to attach wet clothes to a drying frame so they can be air dried outside, though the process is a slow one.
