## AI Etymology
Fester comes from Middle English festren, from Old French festre ('an ulcer, sore'), from Latin fistula ('pipe, ulcer, fistulous sore'). The development is chiefly a borrowing or learned continuation, carrying an older form and meaning into English rather than building the word from a purely native base. In present use, it is used as a verb meaning "to become infected and suppurate, or to grow steadily worse", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as festering and festered and related forms such as fistula, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin fistula, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood is marked by suppurate, ulcerate, rankle, and rot on one side and contrasts such as heal and mend on the other, locating the modern specialization without adding a new origin story.
