سَفِىُّّ

Dust raised, or made to fly, and carried away, or dispersed, by the wind; (S, K;) and (K) so ↓ سَافٍ, (M, K,) i. q. ↓ مَسْفِىٌّ; a possessive epithet, or of the measure فَاعِلٌ in the sense of the measure مَفْعُولٌ. (M. [See another explanation of سَاف voce سَفًا, from the Hamáseh. Freytag explains both سَفِىٌّ and سَافٍ, as on the authority of the K, as epithets applied to the wind, not to the dust.])

Also Clouds; [apparently as being driven by the wind;] synonym سَحَابٌ. (S.)

-A2- And i. q. سَفِيهٌ [Lightwitted, &c.: see 1, last sentence]. (M, K.) [And it seems to be indicated in the S that ↓ سَافٍ is synonym with سَافِهٌ, which is synonym with سَفِيهٌ.]
