Etymology edit

Chang and Eng Bunker, conjoined twins from Siam (modern Thailand), were known as the "Siamese twins".

Noun edit

Siamese twin (plural Siamese twins)

  1. A conjoined twin; one of two people physically joined together.
    • 1857, Herman Melville, chapter XXI, in The Confidence-Man: His Masquerade:
      the two stood together; the old miser leaning against the herb-doctor with something of that air of trustful fraternity with which, when standing, the less strong of the Siamese twins habitually leans against the other.
  2. (linguistics) Either of a pair of words that occur together as an idiomatic expression or collocation, as in "hammer and sickle", "short and sweet", or "spick and span".

Usage notes edit

Some consider the term "Siamese twin" to be offensive, as it inordinately links Thais and Thailand to the birth defect.
