Etymology: Ancient Greek speakers had a plain verb for jabbing something sharp: "kentéō" meant "I prick" or "I goad," and from it they formed "kéntēsis," the act of pricking. The noun carried that literal sense of a puncture, a sharp prod into something. English took the term much later, borrowing it as a medical word for the procedure of piercing a body cavity with a needle or hollow instrument to draw off fluid. The word thus preserves the Greek idea of a deliberate, controlled prick, now applied to surgery and diagnosis rather than to goading animals or driving pins into cloth. Its ending, "-sis," is the common Greek suffix for an action or process, the same pattern seen in words like "diagnosis" and "analysis," which is why the term reads as a clinical procedure name rather than an everyday verb.

Synonyms: puncture, aspiration
