Which word means to perceive or recognize something?

The term "descry" specifically means to catch sight of or to detect something, often from a distance. It implies a sense of recognition or perception, particularly in the context of discovering something that may not be immediately visible or obvious. For example, one might descry a ship on the horizon or a distant landmark. The word conveys an active process of observing and recognizing.

The other options do not pertain to the act of perceiving or recognizing. "Dilatory" refers to something that causes delay or is slow to act. "Desultory" describes an aimless or random approach, often lacking in a clear purpose or plan. "Edifying" means providing moral or intellectual instruction or improvement, which relates to enhancement rather than recognition. Thus, "descry" stands out as the only choice that aligns with the meaning of perceiving or recognizing.
