Watch for a silent k.

Same family: knocks, knocked, knocking, knockout, door-knock. If you can spell one, the shared part carries to the others.

Where it comes from: “Knock” comes from Old English “cnocian,” meaning to strike or rap, and originally imitated the actual sound of hitting something. Over time, it stayed close to its sound-effect roots, which is why it still feels like an onomatopoeic word today.
