‘Metanalysis’ is akin to contamination, except that an older form is actually replaced by one which makes “more sense” to the speakers who introduce the new shape.
- Hockett (1958), Pag. 390

rom time to time it happens that a form of an usual shape- say an unusually long single morph, or an idiomatic combination of morphemes in which the shapes are highly irregular- will be reinterpreted as though it consisted of a sequences of more familiar morphemes represented by more familiar shapes. The general term for this is ‘metanalysis’.
