Etymology Origin:
The word "transfusion" originated in the early 17th century from Latin transfusio, derived from transfundere ("to pour across"). It initially described the literal transfer of liquids (e.g., blood) and later expanded metaphorically to describe the infusion of ideas or qualities. The morphemes trans- and fus- clearly map to the modern spelling, preserving the word's logical structure.
