أَرْوَقُ
1.
[apparently originally signifying Horned:
2.
and hence,] (assumed tropical:) A horse between whose ears the rider extends his spear: when the rider does not thus, he [the horse] is said to be أَجَمُّ. (K.)
3.
Also, applied to a man, (S, Mgh, K,) Having long teeth, with a projecting of the upper over the lower: (JK:) or having long incisors: (Mgh:) or whose upper incisors are longer than the lower, (S, K, TA,) and project over the latter: (TA:) feminine رَوْقَاءُ: (JK, TA:) and plural رُوقٌ; (K, TA;) which is also said to be plural of رُوقَةٌ, and of رَايءِقٌ. (TA.) [In the K is added, after the mention of the plural, وَ كَذٰلِكَ قَوْمٌ رُوقٌ وَ رَجُلٌ أَرْوَقُ: an addition altogether redundant.]
4.
[It seems that it is also synonym with
أَوْرَقُ, as being formed from the latter by transposition; and that hence] one says سَنَةٌ رَوْقَاءُ and سِنُونَ رُوقٌ [meaning (assumed tropical:) A rainless year and rainless years], and عَاثَ فِيهِمْ عَامٌ أَرْوَقُ كَأَنَّهُ
ذِيءْبٌ أَوْرَقُ [meaning (assumed tropical:) A rainless year made mischief, or havock, among them, as though it were a dusky wolf]. (TA.) See also رِوَاق, last sentence.
