ذَوَوِىٌّ
the rel. n. of ذُو; (S, TA;) and of ذَاتٌ also, (S, M, Msb, TA,) the ة of the original being rejected in forming the rel. n.: (S, Msb, * TA:)
ذَاتِىٌّ, as rel. n. of ذَاتٌ, is not allowable: (M:) [but it is much used, mostly in philosophical and religious writings, as meaning Essential, &c.:] they say
الصِّفَاتُ الذَّاتِيَّةُ [meaning The essential attributes]; (Mgh, Msb;) but this is a wrong expression: and
عَيْبٌ ذَاتِىٌّ [An essential, or] a natural, an innate, an original, or a constitutional, fault or imperfection &c. (Msb.)
