ثَاخَ and سَاخَ both signify He, or it, sank into the ground; and Yaạḳoob asserts that the ث in the former is a substitute for the س in the latter. (L, TA.) You say, ثَاخَتْ قَدَمُهُ بِالوَحْلِ, (Ṣ,) or فِى الوَحْلِ, (L,) aor. تَثُوخُ and تَثِيخُ, His foot sank, or entered, into the mire. (Ṣ, L.) And ثَاخَتِ الإِصْبَعُ, aor. as above, (L, Ḳ,) inf. n. ثَوْخٌ, (L,) The finger entered, or sank, into a swollen, or tumid, or a soft, or yielding, substance; (L, Ḳ;) as also سَاخَت, (L,) and تَاخَت: (Lth:) but this last is disapproved by IDrd, and J and others do not mention it. (TA in art. توخ.)
