صَيُّورٌ

Also Judgment, or opinion, (S,) and understanding, or intellect, or intelligence; (S, M, K;) as in the saying, مَا لَهُ صَيُّورٌ [He has not judgment nor understanding]: (S, M:) or a judgment, or an opinion, to which one eventually comes; as in the saying, مَا لَهُ بَدْءٌ وَلَا صَيُّورٌ [He has not a first, nor a final, idea, thought, judgment, or opinion]. (A.)

Also, (O, K;) as AHn says, on the authority of Aboo-Ziyád, (O;) and صَايءِرَةٌ, (K,) Dry herbage or pasture, that is eaten long after its being green: (O, K:) and he adds that no herbs have صَيُّور except such as are of the kinds called الثَّغْر and الأَفَانِى. (O, TA.)

أُمُّ صَيُّورٍ signifies A confused and dubious affair, (M, K,) through which there is no way of passing; as in the phrase وَقَعَ فِى أُمِّ صَيُّورٍ, mentioned by Yaakoob [ISk] in the “ Alfádh ” [according to some of the copies of that work]: originally meaning a [mountain, or hill, such as is termed] هَضْبَة without a pass: but it is more probably صَبُّور [q. v., in article صبر]. (M.)
