Word History
Etymology
borrowed from Latin dīvergere "to proceed in different directions," from dī-, variant before voiced sounds of dis-dis- + vergere "to move downward, slope downward, sink" — more at verge entry 3
Note: The verb dīvergere, attested once in classical Latin, is rare before later medieval and modern Latin, where it appears in scientific and mathematical texts, often as an antonym of convergere "to converge."
