Morphology

knock + on + the + door

The meaning 'to hit a door to attract attention' is directly and transparently derived from the constituents: 'knock' (to strike) + 'on' (on/against) + 'door' (the object). This is a literal, compositional action description found across many languages, and the presence of the article 'the' does not affect predictability, so a B1 learner who knows the words will readily understand it.

Etymology

The phrase knock on the door comes from the simple act of using your hand to knock on a door to get someone's attention. So today it means 'to make a sound at a door to get the attention of the people inside'.
