Fet is an archaic or dialectal variant of fetch, from Old English fetian, feccan ('to bring, fetch'), probably related to Old English fæt ('a step, journey') and the verb 'foot'. The history is deliberately cautious: the proposed comparison is useful for orientation, but the wording leaves room for uncertainty rather than forcing a false certainty. In present use, it is used as a verb meaning "archaic or dialectal: to fetch or bring", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes related forms such as fetch, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Old English fetian, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood includes fetch, bring, retrieve, and get, locating the modern specialization without adding a new origin story.
