سهب1 سَهْبٌ The act of taking. (JK, K.) Yousay, سَهَبَ الشَّىْءَ, aor. ـَ inf. n. سَهْبٌ, He took the thing. (TK.) 2 تَسْهِيبٌ The departure of reason, or intellect: its verb [which was probably سُهِّبَ, like أُسْهِبَ, q. v.,] is obsolete. (TA.) 4 اسهب He went far, or to a great or an extraordinary length, in a thing; for instance, in journeying; as in a trad., in which it is said of horses, or horsemen, أَسْبَهَتْ شَهْرًا They went far for a month; and in eating and drinking; as in another trad.: (TA:) it is from سُهْبٌ, signifying “ a plain and far-extending land; ” as though meaning He traversed a plain and far-extending  tract of land; like as one says أَسْهَلَ and أَحْزَنَ. (Har p. 572.) He (a horse) ran with wide steps, and preceded, or outstripped. (S, TA. [See also سَهْبٌ, below.]) And [hence,] He was, or became, loquacious, or profuse of speech; (IAar, S, K;) like اسهم; (K * and TA in art. سهم;) [and] so اسهب فِى المَنْطِقِ : (JK:) or he doted; or was disordered in his intellect; but when a man makes many mistakes in his speech, you say of him أَفْنَدَ: (As, TA:) or he doted much, or often; or was much, or often, disordered in his intellect: (AO, TA:) [and it seems from an explanation of the part. n. مُسْهِبٌ that it probably signifies also he was eloquent, or profuse of correct speech:] or he was very greedy, and (in some copies of the K “ or ”) covetous, so as to refrain from nothing: (K, TA:) and you say also اسهب كَلَامَهُ He prolonged, or was prolix in, his speech: and فى كَلَامِهِ إِسْهَابٌ In his speech is prolixity. (A, TA.) Also He (a man) gave much, or largely; and so ↓ استهب: (Lth, K:) [or, in this sense,] you say, اسهب فِى العَطَآء. (A.) b2:  اسهبوا They reached sand, in digging [a well], and water came not forth: (S:) or they dug, and came upon sand or a current of air: (K:) or they dug, and came upon a current of air, and the water disappointed them of its coming: (Az, TA:) or they dug without attaining any good: (K:) or اسهب signifies he dug until he reached sand: and, accord. to Th, he dug a well and reached water. (TA.) b3:  اسهبوا الدَّابَّةَ They left the beast alone, or by itself, (K, TA,) to pasture [where it would]. (TA.) A2:  اسهب الشَّاةَ وَلَدُهَا Her young one sucked, (K,) or licked, (TA,) the ewe, or she-goat. (K.) A3:  أُسْهِبَ He (a man, S) lost his reason, (S, K, TA,) as some say, (TA,) from the bite of a serpent, (S, K, TA,) or the sting of a scorpion: (TA:) or his colour became altered in consequence of love or fright or disease: (K:) or, accord. to AHát, اسهب, [so in the TA, in which it seems to be implied that أَسْهَبَ, not أُسْهِبَ, is meant,] inf. n. إِسْهَابٌ, signifies he (a man bitten by a serpent, or stung by a scorpion,) lost his reason and lived. (TA. [See also the part. n., مُسْهَبٌ, below.]) إِسْهَابُ اللُّبِّ [in which the former word is probably the inf. n. of أُسْهِبَ, not of أَسْهَبَ,] means The mind's being  confounded, or perplexed, by [love of] a woman. (JK.) 8 إِسْتَهَبَ see 4, in the middle of the paragraph.سَهْبٌ A desert, or waterless desert; syn. فَلَاةٌ: (S, K:) pl. سُهُبٌ. (TA.)

(TA.) سُهْبٌ A plain and smooth, or plain and smooth and soft, tract of land: pl. سُهُوبٌ: (K:) or the pl. signifies plain and far-extending tracts of land: (JK, A, TA:) or wide land [or lands (for the sing. is expl. in the TA in one place as signifying a wide land)]: (AA, TA:) or سُهُوبُ الفَلَاةِ signifies, (K,) or signifies also, (JK,) tracts, or regions, of the فلاة [i. e. desert, or waterless desert,] in which there is no way. (JK, K.) [See an ex. in a verse cited in art. رقل, conj. 4: and see also سَهْبٌ, above, first sentence.]مُسْهَبٌ, with fet-h to the ه, [contr. to rule, being of the measure مُفْعَلٌ in the sense of the measure مُفْعِلٌ,] Going far, or to a great or an extraordinary length, in a thing: and prolonging.

[with respect to rule], (S, TA,) Loquacious, or profuse of speech: (Az, IAar, ISk, IKt, Zbd, S, K, TA:) or, accord. to Aboo-'Alee El-Baghdádee, as is stated by IB, the former signifies profuse and erroneous in speech: and the ↓ latter, eloquent, or profuse and correct in speech: and in like manner says El-Aalam, adding that ↓ the latter is shown to have this meaning by its being applied to a horse that is fleet, or swift, and excellent: (TA:) or the former signifies doting; or disordered in his intellect: (As, TA:) or doting much, or often; or much, or often, disordered in his intellect: (AO, TA:) [and similar explanations of it will be found below:] other  instances of verbs of the measure أَفْعَلَ having  مُفْعَلٌ as the measure of the part. n. used in the sense of the measure مُفْعِلٌ are أَلْفَجَ and أَحْصَنَ and أَجْرَشَتِ الإِبِلُ and أَهْتَرَ: as used in the first of the senses expl. in this sentence, مُسْهَبٌ is from سُهْبٌ signifying “ a wide land: ” or, as some say, it is from أَسْهَبُوا الدَّابَّةَ, expl. above; as though the person to whom it is applied were left to speak what he would, or made to have ample scope to say what he would. (TA.) b5: Both مُسْهَبٌ and ↓ مُسْهِبٌ signify also Very greedy, and covetous, so as to refrain from nothing.
