Why this word is great
UNWONTEDNESS — [Noun] The quality of being unwonted or unusual; deviation from custom or habit. From unwonted ("unusual, not customary," from un- ("not") + wonted ("accustomed, habitual")) + -ness (noun-forming suffix indicating state or quality), it names the quiet shock of the unfamiliar in the expected. Unlike "rarity" (which tallies scarcity) or "novelty" (which celebrates invention), unwontedness is the unsettling presence of the unscripted—a stranger’s laugh in an empty house, frost blooming on a summer windowpane, or the way a lifelong habit can vanish overnight, leaving only the ghost of its absence. It is the world’s gentle reminder that even the most settled rhythms are provisional.
