superposev.

Brit.

/ˌsuːpəˈpəʊz/,

/ˌsjuːpəˈpəʊz/, U.S.

/ˌsupərˈpoʊz/

Origin: Formed within English, by derivation; modelled on a Latin lexical item, and perhaps also partly modelled on a French lexical item. Etymons: super- prefix, pose v.¹

Etymology: < super- prefix + pose v.¹, after classical Latin superpōnere (see superposit v.) and perhaps partly also after French superposer (1762). Compare earlier superposit v., superposition n.

1. transitive. To place above or on top of something else. Frequently in past participle: (of two or more things) occurring in a vertical series, lying one above another.
