[f. as prec. + -NESS.] The quality or state of being flighty; giddy capaciousness, fickleness or whimsicalness.
1748. Richardson, Clarissa (1811), II. i. 9. I am sensible that I am a little out of season in treating thus ludicrously the subject I am upon, while you are so unhappy; and if my manner does not divert you, as my flightiness used to do, I am inexcusable both to you, and to my own heart: which, I do assure you, notwithstanding my seeming levity, is wholly in your case.
1857. Maurice, Ep. St. John, xiv. 216. There is a flightiness about our talk as if we disdained the earth, and were always trying to mount above it, though we are continually dropping down to it by the force of an irresisstible attraction.
