"a stock of plays, songs, etc., which a performer or company has studied and is ready to perform," 1847, from French répertoire, literally "index, list" (14c.), from Late Latin repertorium "inventory" (see repertory).

1550s, "an index, list, catalogue," from Late Latin repertorium "inventory, list," from Latin repertus, past participle of reperire "to find, get, invent," from re-, here perhaps an intensive prefix (see re-), + parire, archaic form of paerere "produce, bring forth" (from PIE root *pere- (1) "to produce, procure").

The meaning "list of performances an actor or company can stage" is recorded by 1845, from similar use of French repertoire; repertory theater is attested from 1896. Related: Repertorial.

Middle English shep-herd, "man who leads, tends, and guards sheep in a pasture," from Old English sceaphierde, from sceap "sheep" (see sheep) + hierde "herder," from heord "a herd" (see herd (n.)). Similar formation in Middle Low German, Middle Dutch schaphirde, Middle High German schafhirte, German dialectal Schafhirt.

Shepherds customarily were buried with a tuft of wool in hand, to prove on Doomsday their occupation and be excused for often missing Sunday church. Shepherd's pie is recorded from 1877; so called because the meat in it was typically mutton or lamb.

The shepherd's pie, a dish of minced meat with a topping, first surfaces in the 1870s, roughly contemporaneously with the mincing machine which did so much to help establish it in the British cook's repertoire. [Ayto, "Diner's Dictionary"]
