Brit.

/ˌmɛtəˈplastɪk/, U.S.

/ˌmɛdəˈplæstɪk/

Forms: 1600s metaplastick, 1800s– metaplastic.

Origin: Formed within English, by derivation. Etymons: meta- prefix, -plastic comb. form.

Etymology: < meta- prefix + -plastic comb. form. In sense 1a probably after Plato's use of μεταπλάσσειν (see metaplasm n.¹) at Timaeus 50a. In sense 1b after metaplasm n.¹ 1. In senses 2, 3, and 4 after metaplasia n., metaplasis n., and metaplasm n.² respectively. Compare French métaplastique (1845 in sense 1b; 1859 in sense 2). Compare classical Latin metaplasticōs, adverb (representing an unattested Greek *μεταπλαστικῶς), used with reference to words changed in form by poets, in a 2nd-cent. epitome of a 1st-cent. grammarian.
