词源
from Latin， from quattuor 'four'.
▪ I.quadri-|ˈkwɒdrɪ|a first element used in combs. with the sense ‘having, consisting of, connected with, etc. four (things specified)’. The L. quadri- was so employed in a few words during the classical period, as in the ns. quadriduum, quadriennium, quadrirēmis, quadrivium, the adjs. quadrifidus, quadrijugus, and the pple. quadripartītus. In the post-classical and later language such compounds are much more numerous, esp. adj. forms, as quadriangulus, -ennis, -formis, -gamus, -laterus, etc. (See also quadru-.)The earliest examples in English are quadrangle, quadripartite, quadrivial, which are as old as the 15th c.; others, as quadrifid, quadriform, quadrilateral, quadrireme were introduced later, esp. in the 17th c. By far the greater number of quadri- compounds, however, belong to the language of modern science, the employment of the prefix in popular words being much rarer than that of bi- and tri-. A considerable number of those given in the following lists are self-explanatory, and in these cases the definition is omitted.I.
