swift: swift: [OE] The etymological meaning of swift appears to be ‘moving along a course’; ‘speed’ is a secondary development. It goes back ultimately to the prehistoric Germanic base *swei- ‘swing, bend’, which also produced English sweep, swivel [14], and the long defunct swive ‘copulate with’ (a descendant of Old English swīfan ‘move in a course’). Its use as a name for the fast-flying swallow-like bird dates from the 17th century.
=> sweep, swivel
