Etymology
The compound 'mirror-image' is a modern English formation that logically combines two ancient concepts of visual representation. 'Mirror' descends from the Latin verb 'mirari', meaning to wonder or admire, reflecting the awe inspired by clear reflections. 'Image' stems from the Latin 'imago', denoting a likeness or copy. The term's literal meaning, an identical but laterally reversed copy as seen in a mirror, emerged from the physical properties of reflection. This concrete sense later evolved into a powerful metaphor for any precise counterpart or opposite complement, embedding the logic of reflection into abstract comparisons.
