Etymology
The term "chiropractic" is a modern coinage, constructed in the late 19th century from ancient Greek roots to describe a new therapeutic practice. It literally translates to "done by hand," directly combining kheir (hand) and praktikos (practical, performing). This etymology reflects the foundational principle of the discipline: the manual manipulation of the spine and joints to treat ailments. The logic is transparent, as the modern abstract meaning of a system of healing through hand-based adjustment is a direct and intentional application of the combined literal meanings of its Greek components.
Analysis
