أَكْيَاتٌ

i. q. أَكْيَاسٌ, [plural of كَيِّسٌ:] (K:) the Rájiz says,

غَيْر أَعِفَّاءِ وَلَا أَكْيَاتِ

[Not such as abstain from things unlawful and unbecoming, nor ingenious, or acute in mind, &c.]. (TA.) See article س p. 1281 a. Some say, that it it is a word mispronounced: others, that it is formed by the change of س into ت, as in the case of طَسٌّ and طَسْتٌ. (TA.)
