طَغْوَى

a subst. from the verb طَغَا, (K, TA,) [and] so is ↓ طُغْيَانٌ, (Msb,) or the latter is a verbal noun, (S, K,) and, according to Az, so is طَغْوَى, and so too is ↓ طَغْيَا, which latter is said by Zj to be the original of طَغْوَى: (TA:) it is like طُغْوَانٌ and طُغْيَانٌ. (S.) Hence, in the Qur'an, 91:11, كَذَّبَتْ ثَمُودُ بِطَغْوَاهَا [Thamood disbelieved by reason of their exorbitance]; (K, * TA;) meaning that they did not believe when they were threatened with the punishment of their طُغْيَان: or, as is said in the Expos. of Bkh, the meaning is, by reason of their acts of disobedience. (TA.)
