pleo-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly; see e.g. pleocytosis n.

Forms: 1800s– pleio-, 1800s– pleo-.

Origin: A borrowing from Greek, combined with an English element. Etymons: Greek πλείων , πλεῖον , -o- connective.

Etymology: < ancient Greek πλείων (also πλέων ), πλεῖον more (see pleio- comb. form); compare -o- connective. Compare German pleo- (formations in which are found from at least the mid 19th cent.). Compare pleio- comb. form, plio- comb. form, which are etymologically identical, but are now largely distinguished in form in the terminology of different scientific disciplines.Combining with second elements of Greek origin. See etymological note at pleio- comb. form. Attested earliest in the first half of the 16th cent. in the post-classical Latin loan pleonasmus n., subsequently in pleonasm n., and the family of related words, some of which are adaptations from Greek. From the first half of the 19th cent. the combining form occurs in a number of scientific terms, the earliest of which is the French adaptation pleodont n.; shortly afterwards, from the mid 19th cent., formations in English are found (apparently earliest in pleomorphism n.). In some scientific terms, notably in pleochroism n. and the word family of related crystallographical and mineralogical terms, the combining form is apparently always spelt pleo- ; on the other hand, in pleomorphy n. and pleomorphism n. (and to a lesser extent in pleomorphic adj.), it varies between pleio- and pleo-, and it is difficult to tell which of these is more frequent.

Forming nouns and adjectives referring to the presence of, or the condition of having, more than a certain or the usual number of something.
