O.E.
swin "pig, hog," from P.Gmc.
*swinan (cf. O.S., O.Fris. M.L.G., O.H.G.
swin, M.Du.
swijn, Du.
zwijn, Ger.
Schwein), neut. adj. (with suffix
*-ino-) from PIE
*su- (see
sow (n.)). The native word, largely ousted by
pig. Applied to persons from c.1380.
Swineherd is recorded from c.1100 as
swynhyrde;
swinish is from c.1200. Phrase
pearls before swine is from Matt. vii.6; an early Eng. formation of it was:
"Ne ge ne wurpen eowre meregrotu toforan eo wrum swynon." [c.1000]
Which is a misreading of L.
marguerite "daisy" as
margarite "pearl."
