单词 merisis
释义

merisisn.

Brit. /ˈmɛrᵻsɪs/, U.S. /ˈmɛrəsəs/
Origin: Either (i) a borrowing from Greek, combined with an English element. Or (ii) formed within English, by derivation. Etymons: Greek μερίς , -sis suffix; -sis suffix.
Etymology: Either irregularly < ancient Greek μερίς part (see note s.v. mero- comb. form1) + -sis suffix, or independently < meri- (in merismatic adj.) + -sis suffix, perhaps after auxesis n. Compare Byzantine Greek μέρισις < the stem of μερίζειν to divide (see merismus n.) + -σις -sis suffix.
