Etymology: "Fistre" is a rare, now-obsolete English noun that appears in Middle English and early modern writing with the sense of a "fistula," a deep, narrow, pus-discharging ulcer or sinus. Its immediate source is Old French "fistule," which English borrowed from Latin "fistula," meaning a pipe, reed, or tube. The Latin sense of a hollow tube is the key to the medical meaning: a fistula is an abnormal channel, a tube-like passage running from one part of the body to another or to the surface. Alternative spellings such as "fistule" and "fistula" were used alongside "fistre" in medieval and early modern English, and "fistre" was typically used in the Middle English period before the Latin-derived forms became standard in medical writing. The word's forms reflect the French-influenced pathway, while the Latin original remained the basis for the anatomical term.
