vo·​cif·​er·​ous vō-ˈsi-f(ə-)rəs How to pronounce vociferous (audio)
: marked by or given to vehement insistent outcry
vociferously adverb
vociferousness noun

Did you know?

Hear ye! Hear ye! To vociferate is "to cry out loudly" so it’s perhaps unsurprising that the adjective vociferous is used to describe those who are loud and proud, who show their support or displeasure for something or someone by hootin' and hollerin'. Both vociferate and vociferous come from the Latin vociferari, a combining of vox, meaning "voice," with ferre, meaning "to carry." In addition to describing loud and insistent individuals and groups—critics, crowds, fans, et al.—vociferous can be used for anything characterized by loud insistence, as in "vociferous complaints," "a vociferous defense," and "vociferous support."
