• IPA^(key): /məˈtæfəsɪs/

metaphasis (uncountable)

1. The accidental transposition of part of the sounds of two words in a phrase; the production of spoonerisms.
   • 1953, Sir Ernest Barker, Age and Youth: Memories of Three Universities ; And, Father of the Man, page 46:

     'Oxford's great metaphasiarch', as Punch once called him, was seldom guilty of metaphasis, or the transposition of sounds. What he transposed was ideas.

   • 1979, Gore Vidal, Kalki, →ISBN, page 31:

     Dr. Ashok suffered from a mild form of metaphasis. He made Spoonerisms.

   • 1986 October 23, Adrian Room, “Letters”, in London Review of Books:

     But couldn’t it be that there is a distinction to be made between ‘metaphasis’ and ‘metathesis’? The OED defines the latter as ‘the interchange of position between sounds or letters in a word’ (my italics). An example would be Old English bridd becoming modern bird. This leaves ‘metaphasis’ free to describe what Spooner did: transpose sounds between different words, like his classic ‘our queer Dean’.

   • 2009, Denise Sutherland, Word Searches For Dummies, →ISBN, page 76:

     The technical term for this transposition is metaphasis.

   • 1893 February 2, Arthur Lister, “On the division of Nuclei in the Mycetozoa”, in The Journal of the Linnean Society of London: Botany, volume 29, page 531:

2. (biology) Alternative form of metaphysis
   • 2013, B. G. Brogdon, Tor Shwayder, Jamie Elifritz, Child Abuse and its Mimics in Skin and Bone, →ISBN:
