metathesis

 [mĕ-tath´ĕ-sis]
1. artificial transfer of a morbid process.
2. a chemical reaction in which an element or radical in one compound exchanges places with another element or radical in another compound.

me·tath·e·sis

(me-tath'ĕ-sis),
1. Transfer of a pathologic product (for example, a calculus) from one place to another where it causes less inconvenience or injury, when it is not possible or expedient to remove it from the body.
2. In chemistry, a double decomposition, wherein a compound, A-B, reacts with another compound, C-D, to yield A-C + B-D, or A-D + B-C.
