, (M, K,) verbal noun تَذْرِيبٌ, (S,) He sharpened (M, S, K) an iron instrument [such as a sword and a spear-head &c.]; (M;) as also
ذَرَبَ, (M, Msb, K,) aorist
ذَرُبَ
, (M, L, Msb, TA,) according to the K
ذَرَبَ
, but this is without any other authority, and contr. to analogy, as neither its third nor its second letter is a faucial, (TA,) verbal noun ذَرْبٌ; (M, Msb, TA;) and
اذرب. (KL.) Also, verbal noun as above, He poisoned a sword, i. e. steeped it in poison, and, when it was well steeped, took it forth and sharpened it; and
ذَرَبَ, likewise, is allowable. (T, TA.)
