Clearly defined or concentrated; having sharp clarity or attention directed toward something specific.
From English 'in' + 'focus', where 'focus' comes from Latin 'focus' meaning 'hearth' or 'fireplace', later extended to mean 'center of activity' in the 17th century. The compound suggests being centered or concentrated on a particular point.
This word beautifully captures how our attention works like a camera lens - when something is 'in focus,' all the scattered light rays converge to create a crisp, clear image. It's fascinating that we use a metaphor from optics to describe mental concentration and clarity of purpose.
