(S, Msb, TA.) b2:  [Hence,] شَابَتْ رُؤُوسُ الآكَامِ (tropical:)  [The heads, or summits, of the hills became white, or hoary]. (A.) A2:  and شاب الرَّأْسَ It whitened the head: so expl. by ISk as used in the following saying, (S,) ascribed  by J to 'Adee, but it is of 'Abeed Ibn-El-Abras: (IB, TA:) تَصْبُو وَأَنَّى لَكَ التَّصَابِى↓ وَالرَّأْسُ قَدْ شَابَهُ المَشِيبُ [Thou inclinest to silly and youthful conduct: but whence cometh to thee the inclining to such conduct when hoariness, or the entering upon the period of hoariness, hath whitened the head?]. (S, * IB, TA.) [See also 2.]2 شيّبهُ الحُزْنُ, (Ks, S, A,) and شيّب الحُزْنُ رَأْسَهُ, and بِرَأْسِهِ, (Ks, S, Msb, K,) which last is a strange phrase, as it exhibits together two means by which a verb is rendered trans., [namely, the doubling of the medial radical letter of the verb and the introduction of the prep. بِ,] (TA,) Grief  rendered him white-headed, or hoary-headed; (Ks, S, A, Msb, K;) as also ↓ اشابهُ, (A,) and ↓ اشاب رَأْسَهُ and بِرَأْسِهِ.

In the phrase in the Kur [xix. 3], وَاشْتَعَلَ الرَّأْسُ شَيْبًا, (S,) meaning And whiteness of the hair of the head hath spread therein like as the radiance of fire spreads in firewood, (Jel,) [or the head has become glistening with whiteness of the hair, or hoariness,] شيبا is in the accus. case as a specificative: or, accord. to Akh, as an inf. n., as though it were said وَشَابَ الرَّأْسُ شَيْبًا. (S, TA. *) شِيبٌ, of a whip, a genuine Arabic word of wellknown meaning; (S;) The thong (K, TA) at the upper extremity (TA) of a whip: (K, TA:) there are two of such thongs, called شِيبَانِ. (TA.)

S.: see also مِلْحَانُ, and قِمَاحٌ: it is also said that] شِيبَانُ [used alone] is a name of [the month] كانون الاوّل, because of the whiteness of the earth by reason of the hoar-frost and snow.

(TA.) أَشْيَبُ White-haired, white-headed, or horary: (S, A, Mgh, Msb, K:) [it is said to be] anomalous  in form; (S, Mgh, Msb;) for an epithet of this measure is only formed [by rule] from a verb of the measure فَعِلَ, aor. ـْ (S, TA;) and it is a condition of the formation of such an epithet that it must denote a defect or the like, or a colour: but أَشْيَبُ signifies white-headed, or hoaryheaded; [so that it does denote a colour;] and ElKhafájee says that it is reckoned among epithets denoting defects, or blemishes, like أَعْمَى and أَعْرَجُ: (MF, TA:) it is said in the K that it has no فَعْلَآء, i. e., (TA,) the epithet شَيْبَآءُ is not applied to a woman; (Msb, TA;) شَمْطَآءُ being used in its stead; (TA;) though one says شَابَ رَأْسُهَا: (Msb, TA:) [but see Har p. 418, where شَيْبَآءُ is mentioned, applied to a woman, as meaning aged, and white, or hoary, in the head: and see شَيْبَآءُ in art. شوب:] the pl. is شِيبٌ; (S, A, Mgh, Msb, K;) with which is syn. شُيَّبٌ; (TA, as from the K; [but not found by me in the copies of the K to which I have had access;]) and ↓ شُيُبٌ: (K, TA:) this last is said by IM to be allowable in poetry, عَلَى التَّمَامِ [here meaning as though it were a word composed of sound letters]; and this is the assertion of the lexicologists [in general]: ISd thinks it to be pl. of ↓ شَائِبٌ [q. v.], like as بُزُلٌ is of بَازِلٌ; or pl. of ↓ شَيُوبٌ [which app. meansvery white or hoary in the head], accord. to the dial. of the people of El-Hijáz, who say دَجَاجَةٌ بَيُوضٌ and دَجَاجٌ بُيُضٌ. (TA.) b2:  [Hence,] one  says, رَأَيْتُ الجِبَالَ شِيبًا (tropical:)  I saw the mountains white with snow and hoar frost.
