sharpsighted

Sharpsighted is an adjective describing keen visual acuity or the ability to notice fine details at a distance, as well as, in a figurative sense, quick perception. It is less common in modern use than its hyphenated counterpart sharp-sighted or sharp-eyed, but may appear in literature and formal writing as a closed form, sharpsighted.

The term derives from combining sharp, meaning keen, with sighted, meaning having sight. The hyphenated form sharp-sighted is widespread in older or more formal texts, while sharpsighted appears in later periods as a closed compound. The word is typically used to describe humans or animals with acute vision, and it can also describe instruments, organizations, or processes that enable precise perception or detection.

In usage, sharpsighted often characterizes someone who notices small details at a distance or quickly recognizes subtle cues. It can be applied literally to a person, animal such as a raptor, or device that enhances vision, as well as metaphorically to denote perceptiveness or discernment in identifying issues or patterns.

Related terms include sharp-eyed, keen-eyed, and eagle-eyed, which convey similar meaning with varying nuance. See also terms related to perception and attention to detail.
