To stand or prop up s.t. (by supporting the weight of the object with s.t. that is connected to the object such as a kickstand on a motorcycle, one's extended arm and hand acting as a stand when leaning one's body weight slightly to the side, etc.).
The -an is used when trying to see if s.t. will support the weight of s.t.
Stand your motorcycle on top of that cement.
Don't support your weight (with your hand) on that table because it isn't well-made.
