(Msb.) You say, الشَجَرَةُ ↓ اِسْتَأْصَلَتِ The tree [ took root; or] grew, and became firm in its root.

(M: [and so, probably, in correct copies of the K; but in a MS. copy of the K and in the CK; and TA, instead of عَاقِل, the reading in the M, I find عَاقِب.]) ― -b3- Also, (S, * K,) inf. n. as above, (S, TA,) It (judgment, or opinion,) was, or became, firm, or sound, (S, * TA,) or good.

(Msb.) -A2- أَصَلَهُ, [aor. and inf. n. as in what follows next after this sentence,] He hit, or struck, its root, or foundation; that by being which it was what it was, or in being which it consisted; or its ultimate constituent. (A, TA.) ― -b2- And hence, (A, TA,) أَصَلَهُ عِلْمًا, (A, K, TA,) aor. اَصُلَ , inf. n. أَصْلٌ: (TA;) or ↓ اآصَلَهُ [with medd, (which I think to be a mistake, unless this be a dial. var.,) and without علما]; (so in a copy of the M;) (assumed tropical:) He knew it completely, or thoroughly, or superlatively well, syn. قَتَلَهُ, (K,) [i. e.] قَتَلَهُ عِلْمًا, so that he was acquainted with its أَصْل [or root, or foundation, or its ultimate constituent, as is indicated in the A and TA]: (M:) or this is from أَصَلَةٌ, as meaning “a certain very deadly serpent;” (A, TA;) [whence the phrase,] ― -b3- أَصَلَتْهُ الأَصَلَةُ, (K,) inf. n. أَصْلٌ, (TA,) The [ serpent called ] اصلة sprang upon him (K, TA) and slew him.
