muḍāriʿـَيَفْعَلُmaṣdarضَجْعٌ
Core sense — he lay on his side, he slept; he was weak in an affairgenerated
1.1he laid his side on the ground; [he lay upon his side; and simply he lay; and he slept]—اِضْطَجَعَ
maṣdar ضَجْعٌ and ضُجُوعٌ.
It is also explained as synonymous with نَامَ [which has the second and third of the meanings mentioned above], and with اِسْتَلْقَى [which has the third of those meanings].
The ط is substituted for the ت of اِضْتَجَعَ and اِضَّجَعَ and اِلْطَجَعَ (in the CK, wrongly, اطَّجَعَ); the ض in اضطجع is changed into ل, the letter nearest to it in sound, because the combination of two such letters as ض and ط is disliked, the same change occurring in اِلْطِرَادٌ for اِضْطِرَادٌ, though this change is irregular.
أَضْجَعَ likewise has the same meaning as ضَجَعَ, and so does انضجع, as quasi-passive of the transitive verb اضجع.

[According to Freytag, it occurs in the Deewán of the Hudhalees as meaning: he turned aside from the way.]
1.1.2figurative · مجازthe star, or asterism, or the Pleiades, inclined to setting—ضَجَعَ النَّجْمُ

Also اضجع, and ضَجِعَ, of the measure of فَرِحَ, on the authority of IKtt.

Not a mistranscription for ضَجِعَ, as its ism fāʿil shows.

, aor. ضَجَعَ , inf. n. ضَجْعٌ and ضُجُوعٌ , [He lay upon his side; or] he laid his side upon the ground; [and simply he lay; and he slept;] as also اِضْطَجَعَ , (S, Msb, K, TA,) which is also expl. as syn. with نَامَ , [which has the second and third of the meanings mentioned above,] and with اِسْتَلْقَى , [which has the third of those meanings,] (TA,) the ط being substituted for the ت of اِضْتَجَعَ , (Lth, S, Msb,) and اِضَّجَعَ , (S, Msb, K,) and اِلْطَجَعَ , (S, L, K, in the CK [erroneously] اطَّجَعَ ,) the ض in اضطجع being changed into ل , which is the letter nearest in sound thereto, because the combination of two such letters as ض and ط is disliked, (S, L,) the same change occurring in اِلْطِرَادٌ for اِضْطِرَادٌ , (Az, TA,) though this change is anomalous; (L;) and أَضْجَعَ likewise signifies the same as ضَجَعَ ; (Msb;) [and] so does انضجع , (K, TA,) as quasi-pass. of the trans. verb اضجع . (TA.) [And accord. to Freytag, it occurs in the Deewán of the Hudhalees as signifying He declined from the way.] ضَجَعَ النَّجْمُ means [The star, or asterism, or the Pleiades,] inclined to setting; as also ضجّع , (K, TA,) inf. n. تَضْجيعٌ . (TA.) And ضَجَعَتِ الشَّمْسُ is a dial. var. of ضجّعت , (TA,) which means The sun approached the setting; (S, K, TA;) like ضَرَّعَت . (S, TA.) ضَجَعَ فِى أَمْرِهِ He was, or became, weak in his affair; as also اضجع ; and so ضَجِعَ , like فَرِحَ [in measure], on the authority of IKtt. (TA. [See also 2, and 5, and 6.]) And ضُجِعَ فِى رَأْيِهِ [not a mistranscription for ضَجِعَ , as is shown by its part. n., q. v.,] He was, or became, weak in his judgment, or opinion. (TA.)
