The word 干脆 is formed through the conceptual blending of two vivid, sensory images: 干 (gān), meaning "dry" or "dried", and 脆 (cuì), meaning "brittle" or "crisp". It visually evokes the property of something, like dry wood or a cracker, that is completely devoid of moisture and therefore snaps cleanly and decisively without lingering elasticity or resistance. This concrete quality is then metaphorically extended to describe human action or attitude, implying a manner that is straightforward, final, and without hesitation, much like the clean break of something dry and brittle.
