What does knifelike mean?
Knifelike means resembling a knife, especially in shape, sharpness, or pointedness. It is most often used for an edge, blade, or facial feature that appears sharp, narrow, and potentially dangerous. Because the comparison is inherently violent, the adjective can also suggest menace or a threatening capability, although context determines whether the implication is literal or figurative. Writers may use it for a forceful argument, a cutting remark, or exceptionally precise analysis, where it suggests verbal acuity rather than physical violence. Knifelike is a useful word when a description needs to convey more than simple sharpness: it evokes the distinctive shape and concentrated force of a knife. The closed spelling is especially common in American usage, although the hyphenated form “knife-like” is also accepted and frequently encountered in both British and American English.
