1 كَسَبَ  , aor. كَسِبَ , inf. n. كَسْبٌ (S, K, Msb) and كِسْبٌ (K), He collected (wealth &c.]; (S, K;) as also ↓ اكتسبهُ . (S.) This is the original signification. (S.) ― -b2- [Hence,] He gained, acquired, or earned, wealth or the like; as also ↓ اكتسب . (Msb.) كَسَبْتُ شَيْئًا and ↓ اكْتَسَبْتُهُ are syn., [signifying I gained a thing]. (S.) ― -b3- Hence [also], كَسَبَ and ↓ اكتسب (S, K, Msb) and ↓ تكسّب (K) He sought, sought after, or sought to gain, sustenance, or the like, (S, K,) for his family: (Msb:) or كَسَبَ signifies he got, or obtained, or gained, acquired, or earned, [sustenance, &c.]; and ↓ اكتسب , he applied himself with art and diligence [to get, or obtain, or gain, acquire, or earn, sustenance &c.; he laboured to earn, or gain, sustenance]: (Sb, K:) [so] also ↓ تكسّب is explained by تَكَلَّفَ الكَسْبَ he applied himself, as to a task, to gain, &c. (S.) ― -b4- كَسَبَ is also said to signify, and originally, both he sought, or sought after, [sustenance]; and he laboured in seeking, or seeking after, sustenance. (TA.) ― -b5- ↓ اكتسب has a more intensive signification than كَسَبَ; and hence, in the last verse of the second chap. of the Kur [لَهَا مَا كَسَبَتْ وَعَلَيْهَا مَا اكْتَسَبَتْ To it shall be given what reward it hath earned, and upon it shall be executed what punishment it hath drawn upon itself], the latter is used with reference to what is good; and the former, with reference to what is evil. (IJ.) You say, كَسَبَ خَيْرًا (tropical:) [He gained, or earned, or did, good]: and ↓ اكتسب شَرًّا (tropical:) [He gained, or earned, or did, evil]. (A.) ― -b6- [This distinction, however, is not always observed: for] كَسَبَ signifies, He did either a good or an evil deed: [because he who does so earns, or draws upon himself, reward or punishment.] (Jel in ii. 281; and iii. 24; &c.) And ↓ اكتسب He committed an act of which he was accusable. (Jel in xxxiii. 58.) كَسَبَ إِِثْمًا and ↓ اكتسبهُ signify He [committed, or] burdened himself with (تَحَمَّلَ), a sin, or crime. (Msb.) ― -b7- كَسَبَهُ مَالًا, (S, K,) and مالا ↓ اكسبهُ , (IAar, IAth, K,) but the former is the more approved: the latter is by Fr and some others rejected: (TA:) He caused him to gain, acquire, or earn, wealth: (IAth, Msb:) or he assisted him to gain, acquire, or earn, wealth. (IAth.) كسبهُ عِلْمًا He caused him to gain, or acquire, knowledge. (Msb.) [In like manner,] العَبْدَ ↓ اسْتَكْسَبْتُ I caused the slave to gain, or make gain; the verb having here the sense of the measure أَفْعَلْتُهُ; like as اِسْتَخْرَجْتُهُ signifies أَخْرَجْتُهُ. (Msb.) [See an ex. voce أَدِيمٌ.] ― -b8- نَهَى عَنْ كَسْبِ الإِِمَاءِ [He (Mohammad) forbade the making female slaves to earn money, or the like, (by prostitution）]. (TA, from a trad.) ― -b9- مَا كَسَبَ in the Kur cxi, 2, is said to signify His children. A man's children are among the things termed his كَسْب. (TA.) ― -b10- كَسَبَهُ عَجَبًا It occasioned, or caused, him to wonder. (TA, voce أَعْجَبَ.) 4 أَكْسَبَ see 1. 5 تَكَسَّبَ see 1. 8 إِِكْتَسَبَ see 1 throughout. كَسْبٌ  inf. n. of 1. q. v. ― -b2- فُلَانٌ طَيِّبُ الكَسْبِ, (S, K,) and ↓ المَكْسَبِ , and ↓ المَكْسِبِ , (K,) and ↓ المَكْسِبَةِ , and ↓ الكِسْبَةِ , (S, K,) and ↓ الكَسِيبَةِ , (IM,) [Such a one makes good gain: كَسْبٌ &c. signifying gain, acquisition, or earning: and also a deed, whether good or evil]. كُسْبٌ  i. q. كُنجارق [or كَنْجَارَهُ], a Persian word, called by some of the people of Es-Sawád كُسْبَج [or كُسْبَه; i. e., The dregs of sesamegrain, or the like, from which the oil has been expressed]; (TA;) dregs remaining after the expression of oil: (S, K:) [as also كُزْبٌ:] from the Persian كشب, (AM,) [or rather كُسْبَه, or كُسْبَج].

(TA, art. برح.) كَسُوبٌ  [so in the copies of the K in my hands; but by the place in which it is mentioned in the TA, it is implied that it is ↓ كَسُّوبٌ : see also لَسُوبٌ] A thing; anything. مَا لَهُ كَسُوبٌ He has not anything. (K.) -A2- رَجُلٌ كَسُوبٌ, and ↓ كَسَّابٌ , A man who makes much gain. (K.) كُسَيْبٌ  : see كَسَابِ. ― -b2- إِِبْنُ الكُسَيْبِ Bastard. (K.) كَسَّابٌ : see كَسُوبٌ. كَسُّوبٌ A certain plant.

(MF.) [The explanation in the TA, الجَوَارِحُ مِنَ الإِِنْسَانِ وَالطَّيْرِ, seems, at first sight, to signify preyers, whether men or birds: but this meaning I do not think to be the one intended.] أَبُو كَاسِبٍ  The wolf. (K.) اِكْتِسَابِىٌّ  [Acquired knowledge, such as is acquired by study: as also ↓ كَسْبِىٌّ :] opp. to ضَرُورِىٌّ as meaning [natural or instinctive, or] such as the creature has by [Divine] appointment.
