Middle English senden, from Old English sendan "dispatch (as a messenger, on an errand); order or cause to go or pass (from one place to another);" also "send forth, emit; throw, propel, cause to be delivered or conveyed."ETD send (v.).2

This is reconstructed to be from Proto-Germanic *sond- "make to go" (source also of Old Saxon sendian, Old Norse senda, Old Frisian senda, Middle Low German and Middle Dutch senden, Dutch zenden, German senden, Gothic sandjan), causative form of *sinþan "to go, journey" (source of Old English sið "way, journey," Old Norse sinn, Gothic sinþs "going, walk, time"). This in turn is from the PIE root *sent- "to head for, go" (source also of Lithuanian siųsti "send"), for which see sense (n.). For the linguistic connection of "go" and "sense," compare German sinnen (past tense sann) "go over in the mind, review, reflect upon."ETD send (v.).3

send-up (n.)

"a spoof; action of mocking or teasing," by 1958, slang, from the verbal phrase send up "to mock, make fun of" (1931); see send (v.) + up (adv.).

In U.S. slang, send up could mean "convict of crime and imprison" (1852), and in 19c. nautical language it meant "hoist (a mast or yard) into its place aloft."ETD send-up (n.).2
