افخ1 أَفَخَهُ, (A'Obeyd, S, L, &c.,) aor. ـِ inf. n. أَفْخٌ, (L,) He, [or it] struck him, or hit him, [or hurt him,] on the part of his head called the يَأْفُوخ. (A'Obeyd, S, L, Msb, K.) He who pronounces يافوخ without ء says يَفَخَهُ. (Msb.) مَأْفُوخٌ A man having his head broken in the part called the يَأْفُوخ. (L.) يَأْفُوخٌ, (Lth, Az, S, Msb, K,) as also يَافُوخٌ, without ء, but the former is the more correct and the better, (Lth, Az, Msb,) and is of the measure يَفْعُولٌ, (Lth, Az, S, Msb,) whereas the latter is of the measure فَاعُولٌ, (Lth, Az, Msb,) [The top, vertex, or crown, of the head; or the part of the top of the head which is crossed by the coronal suture, and comprises a portion of the sagittal suture;] the part where the anterior and posterior bones of the head meet; (K;) the place that is in a state of commotion in the head of an infant; (S;) the place which, in the head of a child, does not close up until after some years; or does not become knit together in its several parts; and this is where the bone of the anterior part of the head and that of its posterior part meet; (Zj in his “ Khalk el-Insán; ”) the place that is soft, in a child's head, before the two bones called the نَمَّاغَة and رَمَّاعَة meet, between the هَامَة [or middle of the head] and the forehead: (L:) or the middle of the head when it has become hard and strong; before which it is not thus called: (Msb:) pl. يَآفِيخُ; (S;) so in the old lexicons [in general]; but in the T and K يَوَافِيخُ [which is pl. of يافوخ without ء; or, as pl. of يأفوخ, is like تَوَارِيخُ as pl. of تَأْرِيخٌ]; and because of this form of the pl., F says that J is in error in mentioning the word in the present art.: it has been shown, however, that J is not in error in this case. (TA.) — [Hence the saying,] أَنْتُمْ يَآفِيخُ الشَّرَفِ (tropical:)  Ye are the centres and summits of the heads of nobility. (L, from a trad.) and يَأْفُوخُ اللَّيْلِ (assumed tropical:)  The main [or middle] part of the night. (S, K.) — [See also art. يفخ.]
