The term "wert affronted" does not have a specific etymology as it is a combination of words from different origins.
The word "wert" is an archaic form of the second-person singular past tense of the verb "be", typically used in Old English and Middle English.
The term "affronted" derives from the Middle French word "affronter", meaning "to confront", which itself comes from the Latin words "ad" (to) and "frontem" (forehead or front). Over time, "affronter" evolved to mean "to insult" or "to offend". Note that in modern English, "affronted" means to feel offended or displeased.
Therefore, the phrase "wert affronted" would mean "you were offended" or "you were insulted" in older forms of English.
