Etymology
It is formed from English bull + pen, also spelled with a hyphen.[2][3][4] Wilton notes that the combination had long been used literally for a place to keep bulls.[5]
Earliest recorded meaning
A pen of felled pine trees used to hold captured Tories as prisoners: 1809, in Horry and Weems's Life of General F. Marion.[6][5][3] Etymonline dates the word to 1820, in the sense "pen for bulls".[2]
Semantic evolution
In the early 19th century bullpen became American slang for a jail or holding area,[5][6] common in American Civil War camps for prisoners held temporarily;[2] the AHD says it earlier meant a stockade or exercise area for prisoners.[7] The sense lives on in a large holding cell where prisoners wait to go into court.[3][8][9] In baseball the word first named a roped-off area in foul territory or the outfield for the cheap standing crowd, as in the Cincinnati Enquirer of 1877, more than a decade before relief pitchers were allowed.[5] The pitchers' warm-up area is recorded from about 1910 according to Wilton,[5] but only from 1915 according to Etymonline, which derives it from the prison sense.[2] Wilton thinks it came instead from the area for the cheap crowd, where the warm-up area was often later placed, and that it was helped along by the Bull Durham tobacco signs common on outfield fences around 1910.[5] From the pitchers' area the word came to mean a team's relief pitchers as a group.[3] It was also the name of a children's ball game, recorded from 1857 and chiefly in the Midland;[10] Etymonline describes it as a baseball-like game of the late 19th century.[2] Later American slang applied it to an open office area full of desks.[9]
