(TA.) You say, عَثَرَ فِى ثَوْبِهِ [He stumbled, or tripped, upon his garment]. (S, O, Msb.) And فِى أَذْيَالِهِ ↓ خَرَجَ يَتَعَثَّرُ [He went forth stumbling, or tripping, upon his skirts]. (A.) And عَثَرَ بِهِ فَرَسُهُ فَسَقَطَ [His horse stumbled, or tripped, with him, and he fell]. (S, O.) And it is said in a prov., الجَوَادُ قَدْ يَعْثُرُ [The swift and excellent horse sometimes stumbles, or trips]: applied to a person by whom a slip that is not of his nature is seen to have been committed.

(S, O, TA.) ― -b3- And [hence, app.,] عَثَرَ, (Kr, K, TA,) inf. n. عَثْرٌ, (Kr, O, TA,) (assumed tropical:) He lied. (Kr, O, K, TA.) One says, فُلَانٌ فِى العَثْرِ وَالبَائِنِ, meaning (assumed tropical:) [Such a one is occupied] in truth and falsehood [or rather in falsehood and truth]. (O, TA.) ― -b4- And عَثَرَ عَلَيْهِ, (S, A, Mgh, O, Msb,) aor. عَثُرَ (S, O, Msb) and عَثِرَ , (TA,) inf. n. عَثْرٌ and عُثُورٌ, (O, Msb, K, [the latter erroneously written in the CK عَثُور,]) (tropical:) [He stumbled on it; lighted on it by chance;] he got, or obtained, knowledge of it; or sight and knowledge of it; became acquainted with it; knew it; or saw it; (S, A, Mgh, O, Msb, K, * TA;) accidentally, or without seeking; (TA;) [and so عَثَرَ بِهِ; (see an ex. voce أَشْرَسُ;)] and ↓ أَعْثَرَ signifies the same; but accord. to the usage of the Kur-án, you say أَعْثَرْتُ غَيْرِى: so in the Kitáb el-Abniyeh of IKtt. (TA. [See 4.]) You say, عَثَرَ عَلَى سِرِّ الرَّجُلِ (tropical:) He obtained knowledge of, or became acquainted with, the secret of the man [accidentally]. (TA.) [Hence,] فَإِِنْ عُثِرَ عَلَى أَنَّهُمَا اسْتَحَقَّا إِِثْمًا, in the Kur [v. 106], means (tropical:) But if it become known, or seen, (Ksh, Mgh, O, Bd, Jel,) that they two have done what has necessitated sin, (Ksh, Bd, Jel,) and deserved its being said of them that they were sinners. (Ksh.) And عَثَرَ, aor. عَثُرَ , inf. n. عُثُورٌ, as expl. by Lth, means (assumed tropical:) He (a man) entered suddenly, or unexpectedly, upon an affair upon which another had not so entered.

(O.) 2 عَثَّرَ see the next paragraph, in three places. 4 اعثرهُ  He caused him to stumble, or trip; or to fall upon his face; [or simply, to fall;] as also ↓ عثّرهُ ; (K, TA;) [and so بِهِ ↓ عَثَرَ ; (see 1, last sentence, and see also عَاثُورٌ, first sentence;)] said of God. (TA.) IAar cites as an ex., “ فَخَرَجْتُ أُعْثَرُ فِى مَقَادِمِ جُبَّتِى
لَوْلَا الحَيَآءُ أَطَرْتُهُ إِِحْضَارَا
” [And I went forth, made to stumble, or trip, upon the fore parts of my jubbeh: but for the sense of shame, I had made it to fly, in running]: accord. to one relation, however, the verb in question, in this verse, is أَعْثُرُ. (TA.) And اعثرهُ اللّٰهُ is syn. with أَتْعَسَهُ [of which see various explanations in art. تعس]. (TA.) ― -b2- [Hence,] اعثر بِهِ عِنْدَ السُّلْطَانِ, (K,) or عِنْدَهُ ↓ عثّرهُ , (A,) (tropical:) He impugned his character to the Sultán, (A, O, K,) and sought to make him fall into destruction by means of the latter. (A.) ― -b3- And اعثرهُ عَلَيْهِ (tropical:) [He made him to stumble upon it, or to light on it by chance; or] he made him to get, or obtain, knowledge of it, or sight and knowledge of it; to become acquainted with it; to know it; or to see it; (S, A, O, Msb, K; *) accidentally, or without seeking. (B, TA.) Hence the phrase in the Kur [xviii. 20] أَعْثَرْنَا عَلَيْهِمْ; (S, Ta;) in which غَيْرَهُمْ, the objective complement, is suppressed. (TA.) And اعثرهُ عَلَى أَصْحَابِهِ (tropical:) He guided him, or showed him the way, to his companions. (A.) ― -b4- اعثر جَدَّهُ, and ↓ عثّرهُ , (assumed tropical:) He [i. e.

(Kh, Har p. 488.) -A2- عَيْثَرَ الطَّيْرَ [from عَيْثَرٌ] He saw, or beheld, the birds: or he saw that the birds ran: (O:) or he saw the birds running, and augured from them (فَزَجَرَهَا). (K. [But this addition, فزجرها, is evidently taken from an explanation of the words here following.]) A poet says, “ لَقَدْ عَيْثَرْتَ طَيْرَكَ لَوْ تَعِيفُ
” [i. e. Thou sawest, or beheldest, thy birds; &c.: would that thou wouldst augur from them, and take warning]. (O.) And you say, عَيْثَرْتُ الشَّىْءَ I saw, or beheld, the thing; (L, TA;) and individuated it. (TA.) عَثْرٌ  : see عَثَرِىٌّ. عُثْرٌ ذ A lie; or falsehood; (K;) as also ↓ عَثَرٌ .

(TA.) عَثَرٌ ذ : see the next preceding paragraph. عَثْرَةٌ ذ A stumble, or trip, (Msb, TA,) in walking, or going along: pl. عَثَرَاتٌ. (TA.) ― -b2- And [hence,] (tropical:) A slip, lapse, fault, wrong action, or mistake; (S, O, Msb, TA;) so called as being a fall into sin or crime. (Msb.) One says, أَقَالَ اللّٰهُ عَثْرَتَكَ (tropical:) [May God cancel thy slip, lapse, fault, &c.]. (A.) And it is said in a trad., لَا حَلِيمَ إِِلَّا ذُو عَثْرَةٍ i. e. (tropical:) There is no one to be characterized as of a forbearing disposition except he be one who has committed a slip, and becomes admonished thereby, distinguishing the occasions of error so as to avoid them [and to make allowance for others who have done the like]. (TA.) ― -b3- And (assumed tropical:) War, or fight, against unbelievers or others; because war, or fight, is an occasion of frequent stumbling, or tripping: so in a trad., in which it is said, لَا تَبْدَأْهُمْ بِالعَثْرَةِ (assumed tropical:) [Begin not ye with them by war]; meaning invite ye them first to El-Islám or to the payment of the poll-tax; and if they assent not, then have recourse to war. (TA.) عَثِرَةٌ  Land (أَرْض) without herbage, being high, and overspread with عِثْيَر, i. e. dust: (O, TA:) and said to occur in a trad. as the name of a particular land.

Th] says that, thus applied, it is with teshdeed to the ث [i. e. عَثَّرِىٌّ], though not in the sense here following. (TA.) ― -b2- Also (tropical:) A man who does not occupy himself in seeking the things of the present world nor those of the world to come: (O, K, TA:) occurring in a trad., in which such is said to be the most hateful of mankind to God: (O, TA:) in this sense, sometimes written with teshdeed to the ث, (K, TA,) and thus it is accord. to Sh (O, TA) and IAar; (TA;) but correctly without teshdeed: (Th, K, TA:) and said by some to be from عَثَرِىٌّ applied to palm-trees. (O, * TA.) One says also, جَآءَ فُلَانٌ عَثَرِيًّا, meaning (tropical:) Such a one came unoccupied. (O, TA.) عَثَارٌ ذ or عِثَارٌ: see عَاثُورٌ, in six places: -A2- and for عِثَارٌ see also عِثْيَرٌ. عَثُورٌ  [Having a habit of stumbling or tripping, or of falling:] that stumbles, or trips, and falls, much or often. (Har p. 296.) عِثْيَرٌ  , (S, O, K,) not عَثْيَرٌ, for there is not in the language any word of the measure فَعْيَلٌ, with fet-h to the ف, except ضَهْيَدٌ, meaning “ hardy, strong, or robust, ” and this is [said to be] forged, (S, O, [but see ضهيد,]) Dust, (MA, O, K,) syn. غُبَارٌ, (O,) or عَجَاجٌ, and تُرَابٌ, (K,) and thus ↓ عِثْيَرَاتٌ is expl. by Sb; (TA;) or dust rising or spreading; (S, MA; *) as also ↓ عِثْيَرَةٌ ; (TA;) and ↓ عِثَارٌ signifies the same. (MA.) ― -b2- And Clay, or earth, (K, TA,) or dust, or bits of clay or compact earth, (TA,) which one turns over (K, TA) with the extremities of the feet (K) or of the toes, in walking, or going along, no other mark of the foot being seen: (TA:) and an obscure trace or mark, (K, TA,) said to be more obscure than such as is termed أَثَرٌ: (TA:) and so ↓ عَيْثَرٌ , with the ى put before [the ث] and with fet-h to the ع in both [of these senses: misunderstood by SM as meaning “ and with fet-h to the ع in both words, ” i. e. in عثير and عيثر]: (K:) or ↓ عَيْثَرٌ signifies an obscure trace or mark: (S:) and Yaakoob mentions the saying مَا رَأَيْتُ ↓ لَهُ أَثَرًا وَلَا عَيْثَرًا and وَلَا عِثْيَرًا [app. meaning I saw not any trace of him nor any obscure trace]: (S, O:) or ولا عِثْيَرًا means, nor clay, or earth, &c., turned over by the extremities of his feet: (TA:) and it is said that ↓ ولا عَيْثَرًا means, nor bodily form. (O.) And [it is said that] مَا لَهُ أَثَرٌ وَلَا عِثْيَرٌ and ↓ ولا عَيْثَرٌ means He is not known to be a pedestrian by the appearing of his foot-mark, nor to be a horseman by his horse's raising the dust.

(TA.) عَاثِرٌ  [Stumbling, or tripping; &c. ― -b2- And] (assumed tropical:) A liar. (TA.) ― -b3- And one says also جَدٌّ عَاثِرٌ (assumed tropical:) [Fortune, or good fortune, in a falling state: (see 1, near the end:)] pl. عَوَاثِرُ: (TA:) ― -b4- or this may be pl of عَاثِرٌ signifying The snare of a sportsman: ― -b5- or it may be pl. of ↓ عَاثِرَةٌ signifying (assumed tropical:) An accident that destroys, or causes to be overcome, him whom it befalls: (O:) ― -b6- or it may be pl. of عَاثُورٌ [q. v.], the ى being suppressed, (O, TA,) by poetic license, in a verse in which it occurs. (TA.) عَيْثَرٌ  The substance of a thing; its bodily, or corporeal, form; syn. عَيْنٌ and شَخْصٌ. (T, O, L, K, TA. [In this sense, it is said in the TA to be erroneously written in all the copies of the K عَثْيَر, with the ث before the ى; but I find it written عَيْثَر in my MS. copy of the K and also in the CK.]) See also عِثْيَرٌ, in five places. عَاثِرَةٌ  : see عَاثِرٌ. عَاثُورٌ  A pit dug for a lion or other [animal], (S, A, O,) that he may fall into it, (A,) in order that he may be taken: (S, O:) this is the primary signification: (A:) or a thing that is prepared for one to fall into it: (K:) or, as also عثار [i. e. ↓ عَثَارٌ or ↓ عِثَارٌ (see what follows)], a thing by which one is made to stumble and fall; expl. by بِهِ ↓ مَا عُثِرَ : (TA:) the pl. is عَوَاثِيرُ; whence, perhaps, عَوَاثِرُ, by suppression of the ى. (O, TA. [See عَاثرٌ.]) ― -b2- [Hence,] (assumed tropical:) A place of perdition: (TA voce حَاجُورٌ:) or (tropical:) a cause, or place, of perdition or of death: (A, K:) applied to a land. (K.) You say, وَقَعَ فِى عَاثُورٍ (tropical:) He fell into a cause, or place, of perdition or of death. (A, TA.) And فُلَانٌ يَقِى صَاحِبَهُ العَوَاثِرَ (tropical:) [Such a one preserves his companion from the causes, or places, of perdition or of death]. (A.) And it is said in a trad., إِِنَّ قُرَيْشًا أَهْلُ أَمَانَةٍ مَنْ بَغَاهَا العَوَاثِيرَ كَبَّهُ ا@للّٰهُ لِمَنْخِرَيْهِ (assumed tropical:) [Verily the tribe of Kureysh are people of fidelity: whoso seeks for them the causes, or places, of perdition or of death, may God lay him prostrate upon his nostrils]: or, accord. to one relation, عَوَاثِرَ. (O, TA.) ― -b3- And [hence,] (tropical:) Difficulty, or distress; as also عَاثُورُ شَرٍّ: (S, O:) and evil; (K, TA;) like عَاذُورٌ, which is a dial. var. thereof, or an instance of mispronunciation; (S and O in art. عذر;) as also ↓ عَثَارٌ , (accord. to some copies of the K,) or ↓ عِثَارٌ : (thus in other copies of the K and in the TA [in the latter of which it is said to be with kesr; and this I think to be the more probably correct; originally an inf. n.]:) and شَرٍّ ↓ عِثَارُ is said by Fr to signify the same as عَاثُورُ شَرٍّ. (TA.) You say, لَقِيتُ مِنْهُ عَاثُورًا, (As, S, O, TA,) and ↓ عِثَارًا , (TA,) (tropical:) I experienced from him, or it, difficulty, or distress. (As, S, O, TA.)

(TA.) It is the opinion of Yaakoob that the ف in عَافُور is a substitute for the ث in عَاثُور: but Az observes that this is not necessarily the case, as the meaning of difficulty is implied in the root عفر. (TA.) ― -b4- It is said to signify also A kind of snare (مِصْيَدَة) made of bark. (O.) ― -b5- And A channel that is dug for the purpose of irrigating thereby a palm-tree such as is termed بَعْلٌ.
