زلغبQ. 4 اِزْلَغَبَّ, said of a young bird, Its feathers came forth: (S in art. زغب, and K:) or its feathers began to come forth, (Lth, TA,) before  their becoming black. (TA.) Also said of plumage, It began to come forth. (Lth, TA.) and said of hair, (S in art. زغب, and K,) as also ازلعبّ, (TA,) It grew forth after having been shaven: (S, K:) it began to grow forth, soft: and said of the hair of an old man, i. q. اِزْغَابَّ [it was, or became, downy]. (TA.) Accord. to the S, and AHei and IKtt and others, it belongs to art. زغب, like as اِزْلَعَبَّ is held by them to belong to art. زعب; but accord. to the K, the ل is radical, and therefore this is its proper place. (TA.)
