شتم1 شَتَمَهُ, (MA, Msb, K,) aor. ـِ (Msb, K) and شَتُمَ, (K,) inf. n. شَتْمٌ (S, MA, Msb, K) and مَشْتَمَةٌ and مَشْتُمَةٌ, (K, TA,) the last of these [written مَشْتِمَة in the CK] with damm to the ت, or this and the next before it, though said to be inf. ns., may be simple substantives, as A'Obeyd  inclines to think them, (TA,) He reviled him, vilified him, upbraided him, reproached him, defamed him, or gave a bad name to him; (S, * MA, K, TA;) syn. سَبَّهُ: (K, TA:) or, as some say, شَتْمٌ signifies [the addressing with] foul  speech, without قَذْف [here meaning the casting an accusation, though commonly used and expl. as syn. with شَتْمٌ]: (TA:) and ↓ شاتمهُ signifies the same as شَتَمَهُ, (MA, Msb,) being a rare instance of a verb of the measure فَاعَلَ denoting an act of a single agent when it has an unaugmented verb of the same radical letters [and the same signification], as صَادَمَهُ الحِمَارُ meaning صَدَمَهُ, and زَاحِمَهُ meaning زَحَمَهُ. (Msb.) Hence the saying, فَإِنْ شُتِمَ فَلْيَقُلْ إِنِّى صَائِمٌ [And if he be reviled, let him say, Verily I am fasting], which may mean that he should say this with his tongue, which is the more proper meaning, or mentally: or ↓ فَإِنْ شُوتِمَ, which is allowable, though the former is the more proper. (Msb.) b2:  شاتمهُ فَشَتَمَهُ: see 3.A2:  شَتُمَ, aor. ـُ (S, K,) inf. n. شَتَامَةٌ (S, IB) and شَتَمٌ, (IB, TA,) (assumed tropical:)  He (a man, S) was, or became, displeasing, or hateful, in countenance. (S, K.) A3:  [شَتِمَ, trans. by means of ب, expl. by Golius as meaning He rejoiced at evils, or misfortunes, of an enemy, is, I doubt not, a mistake for شَمِتَ; though it might be supposed to be formed by transposition, like جَبَذَ from  جَذَبَ.]2 شتّم, accord. to Reiske, said of a camel when haltered, and of a lion, as mentioned by Freytag, signifies (assumed tropical:)  He was harsh, and surly, in countenance, and uttered a grumbling sound: if  used, it must be شُتِّمَ, agreeably with the part. n., expl. below.]3 مُشَاتَمَةٌ is syn. with مُسَابَّةٌ, (S,) signifying  The reviling, vilifying, upbraiding, reproaching, defaming, or giving a bad name to, each other: (KL:) and [in like manner] ↓ تَشَاتُمٌ is syn. with  تَسَابٌّ, (S,) signifying as above [but used in relation to two persons and more than two]: (KL:) you say, شَاتَمَا and ↓ تَشَاتَمَا meaning تَسَابَّا [They reviled, vilified, &c., each other]: (K:) and ↓ تشاتموا They reviled, &c., one another; like  تَسَابُّوا. (MA.) [شاتمهُ may therefore be rendered He reviled him, &c., being reviled, &c., by him: but sometimes it is syn. with شَتَمَهُ:] see 1, in two places. b2:  One says also, ↓ شَاتَمَهُ فَشَتَمَهُ, aor. ـُ meaning [He vied, or contended, with him in reviling, vilifying, &c.,] and he overcame him [therein, i. e.] in reviling, &c. (TA.) 5 تشتّم is said by Freytag to signify He exposed himself to contumelies; on the authority of the Ham p. 310: but I there find only the part. n., مُتَشَتِّمٌ, signifying as expl. below: so that the verb, if used, means he became exasperated by reviling, vilifying, &c., and addressed, or applied, himself thereto. b2:  He also explains it as signifying (assumed tropical:)  He contracted the face very austerely; on the authority of the Deewán of the Hudhalees.]6 تَشَاْتَمَ see 3, in three places.شِتَامٌ: see the next paragraph.شَتِيمٌ: see مَشْتُومٌ. b2:  Also (assumed tropical:)  Displeasing, or hateful, in countenance; (S, K;) applied to a man, and to a lion; (S;) and to an ass, as meaning thus, and foul, or ugly: (TA:) or to a lion as meaning (tropical:)  grim-faced; or stern, austere, or morose, in countenance; as also ↓ مُشَتَّمٌ; and ↓ شَتَّامَةٌ; (K, TA;) the last like جَبَّانَةٌ [in measure, but in the CK written شَتامَة]. (TA.) One  says, فُلَانٌ شَتِيمُ المُحَيَّا (assumed tropical:)  Such a one is displeasing, or hateful, in countenance. (S.) A2:  Also, and ↓ شِتَامٌ, An obstruction (سُدَّة) of the fauces, combined with foulness, or ugliness, of face. (TA.) شَتِيمَةٌ a subst., (S, Msb, K, and Ksh in lxxiv.41, [by Bd, in explaining the same passage of the Kur, improperly said to be an inf. n.,]) from  شَتَمَهُ, (Msb, K,) in the sense of شَتْمٌ [meaning The act of reviling, vilifying, or upbraiding; reproach, obloquy, or contumely]; (S, * and Ksh ubi suprà;) as also ↓ مَشْتَمَةٌ, and ↓ مَشْتُمَةٌ, or, as mentioned above, [see 1, first sentence,] these two are inf. ns. (TA.) شَتَّامٌ [One who reviles, &c., much]. (Ham p.310.) شَتَّامَةٌ One who reviles, &c., [very] much. (TA.) b2:  See also شَتِيمٌ.شَاتِمٌ act. part. n. of 1, Reviling, &c. b2:  It is also said by Golius, on the authority of the Mirkát el-Loghah, to signify Rejoicing at another's evils, or misfortunes: but this I believe to be a mistake for شَامِتٌ: see 1, last sentence.]الاشتيام, with kesr, [which seems to indicate that it is الإِشْتِيَامُ,] is expl. by IB as meaning رئيس الركاب [app. رَئِيسُ الرُّكَّابِ The headman, or master, of the riders: but whence this is derived I know not, unless it be arabicized, from the Pers\. أُسْتَا يَام (if there be such an appellation), meaning “ the master of the post-horse ”]. (TA.) مَشْتَمَةٌ and مَشْتُمَةٌ: see شَتِيمَةٌ.مُشَتَّمٌ: see شَتِيمٌ; and see also مُشَبَّمٌ.مَشْتُومٌ Reviled, vilified, upbraided, reproached, defamed, or called by a bad name: and so with ة applied to a female, as also ↓ شَتِيمٌ; (K, TA;) this last, without ة, mentioned on the authority of Lh. (TA.) مُتَشَتِّمٌ Exasperated by reviling, &c., and addressing, or applying, himself thereto. (Ham p. 310: there expl. by the words متحكك بالشتم ومعترض له [i. e. مُتَحَكِّكٌ بِالشَّتْمِ وَمُعْتَرِضٌ لَهُ: see 5].)
