ö́ḳaf - to keep silence (LS 496; CSOL I 469; CSOL II 385 )

As argued by M. Bittner (1911:81) and W. Leslau, Proto-MSA *wḳf ‘to be silent’ is likely related to Arb. wqf ‘to become still, to stop, to stand’. See further DRS 609. Any connection with Akk. ḳâpu ‘to buckle, to collapse’? (Kogan 2015:576)
