ولج1 وَلَجَ, aor. ـِ inf. n. وُلُوجٌ and لِجَةٌ; and ↓ إِتَّلَجَ; (S, K;) and ↓ تولّج; (L;) He, or it, entered. (S, K.) You say وَلَجَ البَيْتَ, and ↓ اتّلجه, and ↓ تولّجهُ, He entered the house. (L.) And وَلَجَ الشَّىْءُ فِى غَيرِهِ The thing entered into another thing. (Msb.) As is said in the S and L, Sb says that وَلَجَ has for its inf. n. وُلُوجٌ, which is of one of the measures of the inf. ns. of intrans. verbs, because the meaning [of وَلَجْتُ البَيْتَ] is وَلَجْتُ فِيهِ: and it is said in the M, that Sb holds the intermediate particle to be dropped: but Mohammad Ibn-Yezeed holds the verb to be trans. without an intermediate particle. MF observes, that Sb's words appear to make ولج a trans. verb, which no one asserts it to be: that if he mean that it has as its complement a noun in the acc. case as an adverbial noun of place, it is like دَخَلْتُ and other intrans. verbs: but if he mean that it governs a simple objective complement, like ضَرَبْتُ زَيْدًا, his opinion is not correct. (TA.) 4 اولج, (S, K,) inf. n. إِيلَاجٌ; (Msb;) and ↓ إِتَّلَجَ, as in the CK and in several MS. copies of the K) or أَتْلَجَ, (as in the L, and all the copies of the K consulted by SM, in this art., and in art. تلج,) in which ت is substituted for و, and this is the correct reading; (TA;) He, or it, caused to enter; introduced; inserted. (S, K.) b2:  The expression in the Kur. [xxii. 60; and other chapters,] يُولِجُ اللَّيلَ فِى النَّهَارِ وَيُولِجُ النَّهَارَ فِى اللَّيْلِ signifies He maketh the night, by increasing it, to enter into, [or encroach upon,] the day, and maketh the day, in like manner, to enter into, [or encroach upon,] the night: (Jel:) or He increaseth the night with a part of the day, by taking from the latter and adding to the former, and in like manner increaseth the day with a part of the night. (S.) b3:  [اولج is often used for اولج ذكره; and hence as meaning Inivit.]5 تَوَلَّجَ see 1.8 إِوْتَلَجَ see 1 and 4.رَجُلٌ خُرَجَةٌ وُلَجَهٌ, (S,) and ↓ خَرَّاجٌ وَلَّاجٌ, and ↓ خَرُوجٌ وَلُوجٌ, (TA,) A man frequently going, or coming, out and in. (S, TA.) [This is the primary meaning: for others see art. خرج.]وَلَجَةٌ A place, (S,) or a cavern, in which passengers shelter themselves from rain &c.: pl. أَوْلَاجٌ and وَلَجٌ, (S, K,) [or rather the latter, which is omitted in the CK, is a coll. gen. n., of which ولجة is the n. un.] or وُلُجٌ. (L.) b2: Also, A bend, or place of bending, of a valley: (IAar:) pl. as above. (K.) وَلُوجٌ and وَلَّاجٌ: see وُلْجَةٌ.وَلِيجَةٌ Anything that is introduced, or inserted, into a thing, and that does not belong to it: any such thing is termed a وليجة of a thing. (A'Obeyd.) b2:  هُوَ وَلِيجَتُهُمْ He is an adherent to them; (K;) one who has entered, or become introduced, or included, among them,] and not belonging to them. (TA.) Pl. وَلَائِجُ. (TA.) b3:  وَلِيجَةٌ (assumed tropical:)  A particular, or special, intimate, friend, or associate, of a man; syn. خَاصَّةٌ (S, K) and بِطَانَةٌ (S) and دَخِيلَةٌ: (K:) by these syns. A'Obeyd explains it in the Kur. ix. 16: and it is applied to one and to more than one: (TA:) or one whom a person takes to rely upon, or to place confidence in, not being of his family: (K:) and so some explain the word in the verse above referred to: (TA:) or it there signifies an intimate friend who is one of the polytheists. (Fr.) وَالِجَةٌ i. q. دُبَيْلَةٌ, (K,) i. e., A certain disease in the belly. (TA.) A pain that attacks a man; or a pain in a man; وَجَعٌ يَأْخُذُ الإِنْسَانَ, (so in two copies of the S, and in the L,) or وَجَعٌ فِى الإِنْسَانِ: (so in the TA and a MS. copy of the K:) or a pain that attacks the teeth; or a pain in the teeth; وجع يأخذ الأَسْنَانَ, (so in a copy of the S,) or وجع فى الأَسْنَانِ.

(S.) مَوْلِجٌ A place of entrance; a place into which one enters: (TA:) pl. مَوَالِجُ. (S.) [See its contr. مَخْرَجٌ.]مَوْلُوجٌ A man attacked by the disease called وَالِجَة, or دُبَيْلَة. (K, TA.)
