“mean” vs. “mien”
Use "mean" for its common verb, adjective, or statistical-average senses; reserve "mien" strictly for the formal literary noun describing a person's bearing or expression.
mean
"Mean" is a highly versatile word: as a verb, it signals intent or signification ("what do you mean?"); as an adjective, it can describe unkindness ("that was a mean thing to say") or, in mathematics and statistics, an average value ("the mean of these numbers"); and as a noun, it names that same statistical average or, in the plural "means," resources or method ("by any means necessary"). It comes from Old English "mænan" (to intend, to signify), with the statistical sense borrowed separately, much later, from Latin "medianus" via French, making "mean" a word with two genuinely different historical strands feeding its modern range of meanings.
mien
"Mien" is a formal, somewhat literary noun describing a person's manner, bearing, or overall appearance and demeanor ("she carried herself with a dignified mien"). It comes from Middle French "mine" (facial expression, appearance), likely influenced in English spelling by the older word "demean" or "demeanor," which shares the same underlying idea of outward bearing.
The real distinction
"Mean" and "mien" are true homophones in most accents, both landing on the same vowel sound, but they occupy almost entirely separate registers of English: "mean" is one of the most common, everyday words in the language, doing double or triple duty across verb, adjective, and noun roles, while "mien" is a rare, formal word that appears mainly in literary or elevated prose describing someone's outward bearing or expression. Because "mien" is genuinely uncommon, most writers will simply never need it and can safely assume that any instance of this sound in ordinary writing is "mean." The word "mien" tends to surface specifically in physical descriptions of a person's carriage or expression — a character's "haughty mien," a "gentle mien," a "weary mien" — almost always paired with an adjective describing demeanor, a pattern distinct from any of the common uses of "mean." If you're reading or writing formal literary description and encounter this sound modified by an adjective describing someone's bearing or expression, "mien" is likely intended; in every other context, from casual conversation to technical or statistical writing, "mean" is almost certainly correct. Because "mien" is rare enough that many fluent English speakers have never needed to spell it, this pair causes far fewer real-world errors than most homophone confusions in this list, mainly showing up when a reader encounters "mien" in print and mistakes it for a typo of the far more familiar "mean." It's also worth knowing that 'mean' carries a third common adjective sense beyond unkindness and average — 'skilled' or 'impressive,' as in the informal phrase 'she plays a mean guitar' — yet another meaning layered onto this already versatile word, none of which has any bearing on the separate, much rarer 'mien.'

Memory trick
"Mean" is everywhere in ordinary speech, so treat it as your default; only reach for "mien" when you're specifically describing someone's outward bearing in a formal or literary way. A helpful hook: "mien" looks like a cousin of "demeanor," and both words describe how someone carries themselves — if "demeanor" or "bearing" could replace the word, you want "mien," not "mean."
