Literary notes about Knock (AI summary)
In literature, the word "knock" functions on multiple levels. It often denotes a literal signal of arrival—a door being rapped to announce a visitor or an unfolding event, as seen when a knock foretells unexpected company or pivotal moments ([1], [2], [3]). At the same time, authors employ it figuratively to suggest impact or confrontation, whether it be the forceful assertion of strength in a challenge ([4], [5]) or the opening of one's inner thoughts and barriers ([6]). This dual capacity enriches narratives by balancing tangible action with metaphorical resonance, drawing readers into both the immediate scene and the deeper thematic undercurrents of the text ([7], [8]).
