جلس1 جَلَسَ, (S, A, Msb, K,) aor. ـِ (A, K,) inf. n. جُلُوسٌ (S, A, Msb, K) and ↓ مَجْلَسٌ, (S, A, K,) He placed his seat, or posteriors, upon rugged [or rather elevated] ground, such as is termed جَلْسٌ: this is the primary signification: (TA:) [and hence,] He sat; i. q. قَعَدَ [when the latter is used in its largest sense]: (Msb, and so S and L and A and K in art. قعد:) you say, جَلَسَ مُتَرَبِّعًا and قَعَدَ مُتَرَبِّعًا [He sat cross-legged]: (Msb:) accord. to El-Fárábee and others, contr. of قَامَ; and thus it has a more common application than قَعَدَ [when the latter is used in its most proper and restricted sense]: (Msb:) but قَعَدَ also signifies the contr. of قَامَ: ('Orweh Ibn-Zubeyr, L in art. قعد:) properly speaking, جَلَسَ differs  from قَعَدَ; the former signifying he sat up; or sat after sleeping, or prostration, (Msb,) or after lying on his side; (B, TA;) and the latter, he sat down; or sat after standing: (Msb, B, TA: and see other authorities to the same effect in art. قعد:) for جُلُوسٌ is a change of place from low to high, and قُعُودٌ is a change of place from high to low: and one says, جَلَسَ مُتَّكِئًا, but not قَعَدَ مُتَّكِئًا, meaning [He sat] leaning, or reclining, upon one side: (Msb:) but both these verbs sometimes signify he was, or became: and thus, [it is said,] جَلَسَ مُتَرَبِّعًا and فَعَدَ مُتَرَبِّعًا signify  he was, or became, cross-legged: and جَلَسَ بَيْنَ شُعَبِهَا الأَرْبَعِ in like manner signifies he was, or became, [between her four limbs,] (El-Fárábee, Msb,) because the man, in this case, is resting upon his own four limbs. (Msb.) [جَلَسَ مَعَهُ and جَلَسَ إِلَيْهِ, like خَلَا معه and خلا اليه, signify the same; i. e. He sat with him: or the latter, he sat by him; like “ assedit ei. ”] An instance of the inf. n. مَجْلَسٌ is found in a trad., in which it is said, فَإِذَا أَتَيْتُمْ إِلَى المَجْلِسِ فَأَعْطُوا الطَّرِيقَ حَقَّهُ [But when ye come to sitting, perform ye the duties relating to the road]. (TA.) [The trad. commences thus: إِيَّاكُمْ وَالجُلُوسَ عَلَى الطُّرُقَاتِ Beware ye of sitting on the roads: and then, after the words before cited, (in which, however, in my copy of the Jámi' es-Sagheer, instead of المجلس, I find المَجَالِسِ, which is pl. of المَجْلِسُ,) it is added that the duties thus alluded to are the lowering of the eyes, the putting away or aside what is hurtful or annoying, the returning of salutations, the enjoining of that which is good, and the forbidding of that which is evil.] b2: جَلَسَتِ الرَّخَمَةُ (tropical:)  The aquiline vulture lay upon its breast on the ground; syn. جَثَمَت: a saying applied to him who is of the seceders. (A, TA.) [See also قَعَدَ.] b3:  جَلَسَ also signifies (assumed tropical:)  It (a thing, as, for instance, a plant,) remained, or continued. (AHn, TA.) b4:  Also, (aor.جَلِسَ, inf. n. جَلْسٌ, TA,) He came to الجَلْس, (TA,) or [the high country called] Nejd: (T, S, A, TA:) and in like manner said of a cloud; it came to Nejd. (TA.) 3 جالسهُ, inf. n. مُجَالَسَةٌ and جِلَاسٌ, [He sat with him.] (TA.) You say, لَا تُجَالِسْ مَنْ لَا تُجَانِسْ [Sit not with him with whom thou wilt not be congenial]. (A, TA.) And كَرِيمُ النِّحَاسِ طَيِّيبُ الجِلَاسِ [Generous in origin, or disposition; pleasant to sit with;] is said of a man. (TA.) 4 اجلسهُ [He seated him; made him to sit: or he made him to sit up]: (S, K, TA:) he gave him place, or settled him, (مَكَّنَهُ,) in sitting. (TA.) 6 تجاسلوا [They sat together; one with another;] (S, A, TA;) فِى المَجَالِسِ [in the sittingplaces]. (S.) 10 استجلسهُ [He asked him, or desired him, to sit: or to sit up.]. You say, رَآنِى قَائِمًا فَاسْتَجْلَسَنِى[He saw me standing, and he asked me, or desired me, to sit]: (A, TA:) but this is at variance with what we have mentioned in the beginning of the art., respecting the distinction [between جَلَسَ and قَعَدَ]. (TA.) جَلْسٌ Rugged ground or land: (S, K:) this is the primary signification. (TA.) b2:  [Also, app., Elevated ground or land:] a place elevated and hard: or, as some say, a tract of land extending widely.
