سَطَعٌ
1.
2.
A clapping with the hands, or striking with one hand upon the other,
or upon the hand of another: (K:) or a striking a thing with the palm of the hand, or with the fingers. (TA.) And The sound of a striking or throwing: as in the saying, سَمِعْتُ لِوَقْعِهِ سَطَعًا
شَدِيدًا [I heard, in consequence of its falling, a loud sound of a striking or throwing]. (K.) It is with fet-h to the medial radical because it is an onomatopœia, not an epithet nor a verbal noun, for onomatopœias are sometimes made to differ [in form] from epithets. (Lth, K.)
