meconoisinn.

Brit.

/ˌmiːkəˈnəʊɪsɪn/, U.S.

/ˌmɛkəˈnoʊəs(ə)n/,

/ˌmikəˈnoʊəs(ə)n/

Forms: 1800s– meconiasin, 1800s– meconoiosine, 1800s– meconoisin.

Origin: Probably a variant or alteration of another lexical item. Etymon: meconine n.

Etymology: Probably an alteration of meconine n., with insertion of an arbitrary element (which appears to have varied between -oios- , -ias- , and -ois- ); compare -in suffix¹.With the form meconoiosine perhaps compare laudanosine n. The form meconiasin is perhaps remodelled partly after meconia n. N.E.D. (1906) gives the headword spelling meconisin , with the pronunciation (mikǫ·nisin) /miːˈkɒnɪsɪn/, based on a misreading of the form meconoisin in quot. 1890.

Chemistry. Now rare.

A neutral crystalline compound, C₈H₁₀O₂, present in opium.
