send: [OE] English shares send with the other Germanic languages – German senden, Dutch zenden, Swedish sönda, and Danish sende. These all go back to a prehistoric ancestor *santhjan, which originated as a causative derivative of a base denoting ‘go, journey’ – so etymologically send means ‘cause to go’.

Old English sendan "send, send forth; throw, impel," from Proto-Germanic *sandijan (cognates: Old Saxon sendian, Old Norse and Old Frisian senda, Middle Low German and Middle Dutch senden, Dutch zenden, German senden, Gothic sandjan), causative form of base *sinþan, denoting "go, journey" (source of Old English sið "way, journey," Old Norse sinn, Gothic sinþs "going, walk, time"), from PIE root *sent- "to head for, go" (cognates: Lithuanian siusti "send;" see sense (n.)).

Also used in Old English of divine ordinance (as in godsend, from Old English sand "messenger, message," from Proto-Germanic *sandaz "that which is sent"). Slang sense of "to transport with emotion, delight" is recorded from 1932, in American English jazz slang.
