Why this word is great
VELLEITY — [Noun] A slight wish or inclination not strong enough to lead to action. From Medieval Latin velleitās, from Latin velle ("wish, will"). Unlike "volition" (which marshals action) or "yearning" (which aches with unmet longing), velleity is the ghost of desire—barely felt, barely acknowledged. It is the half-formed thought of calling an old friend while the phone stays in your pocket, the flicker of ambition to learn the piano as your fingers rest inert on the keys, the book bought and never read. A velleity is the shadow of a choice, so faint it barely disturbs the air.
