alterni-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: A borrowing from Latin. Etymon: Latin alterni-.

Etymology: < scientific Latin alterni-, combining form (in e.g. alternifolia , alternifolium (1753 as specific epithets)) of classical Latin alternus altern adj.; compare -i- connective. Compare French alterni-, a small number of formations in which is found from the first half of the 19th cent., e.g. alternifolié alternifoliate, alternipenné alternipinnate (both 1838).Found in a small number of formations (all biological terms) exemplified below. Combining with second elements of Latin origin.
