Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Perhaps alteration (influenced by Guinea, used as a name for any faraway unknown country) of Guiana.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

The origin of "guinea" in "guinea pig" is hard to explain. One theory is that the animals were brought to Europe by way of Guinea, leading people to think they had originated there. "Guinea" was also frequently used in English to refer generally to any far-off, unknown country, and so the name may simply be a colorful reference to the animal's foreignness. Others believe "guinea" may be an alteration of the word coney ("rabbit"); guinea pigs were referred to as "pig coneys" in Edward Topsell's 1607 treatise on quadrupeds.

    In Western societies, the guinea pig has enjoyed widespread popularity as a household pet since its introduction by European traders in the 16th century. Their docile nature, their responsiveness to handling and feeding, and the relative ease of caring for them, continue to make the guinea pig a popular pet. Organizations devoted to competitive breeding of guinea pigs have been formed worldwide, and many specialized breeds of guinea pig, with varying coat colors and compositions, are cultivated by breeders.

    "Guinea pig" is also used as a metaphor in English for a subject of experimentation; this usage became common in the first half of the 20th century. Biological experimentation on guinea pigs has been carried out since the 17th century.

  • THE GUINEA PIG

    There was a little Guinea-pig,

    Who, being little, was not big;

    He always walked upon his feet,

    And never fasted when he eat.

    When from a place he ran away,

    He never at that place did stay;

    And while he ran, as I am told,

    He ne'er stood still for young or old.

    He often squeaked, and sometimes vi'lent,

    And when he squeaked he ne'er was silent:

    Though ne'er instructed by a cat,

    He knew a mouse was not a rat.

    One day, as I am certified,

    He took a whim, and fairly died;

    And as I'm told by men of sense,

    He never has been living since!

    Anon.
