Definition

To strike (a surface) with repeated or intentional motion, usually with the knuckles or a tool, often for the purpose of making one’s presence known or gaining entry; by extension, to make a request or take action to gain attention in a figurative sense. Primary use is to knock (on a door), but can also mean to strike or beat in certain contexts. Figuratively, may imply asking, requesting, or petitioning persistently.

Semantic Range

to knock (on a door), to rap, to strike, to beat lightly, to request entry, to ask or petition persistently (figurative)

Root / Etymology

Apparently a primary verb of uncertain etymology, with possible onomatopoeic origins reflecting the sound of striking or rapping.

Historical & Contextual Notes

κρούω occurs in classical Greek with the primary meaning 'to strike, knock' (as on a door, shield, or other hard surface). In Hellenistic and Koine Greek, as reflected in the New Testament (e.g. Matt 7:7, Luke 11:9), it most often refers to knocking on a door to request entry. The act of κρούω can be both literal and metaphorical—the latter use is especially found in didactic sayings (as in 'knock, and it shall be opened to you'). The verb retains its core physical sense throughout Greek literature, but its metaphorical extension is particularly prominent in parabolic and instructive contexts, where it denotes persistence, request, or an approach for assistance. The term is distinct from more violent terms for striking (e.g., τύπτω) and from the general sense of calling (φωνέω). English translations typically render it as 'knock,' but the idiomatic force is sometimes broader, including 'request' or 'petition.' The Septuagint uses other verbs for physical striking, reserving κρούω primarily for the act of knocking related to doors or entry.

Original Strong's Gloss (1890)

apparently a primary verb; to rap:--knock.
