expression, ichidan verb
shut a door
A somewhat literary or old-fashioned expression for closing a door, especially a sliding door or shutter. In modern casual speech, 戸を閉める is more common.
夜になったので、戸を立てた。
As night fell, I shut the door.
More common modern expression for shutting a door. 戸を立てる has a slightly more formal or literary feel.
The verb 立てる (to stand, set up) here carries an older sense of 'to close' or 'to shut', seen in classical Japanese. The exact historical derivation is uncertain.
