- adj. Noisily and stubbornly defiant; aggressively boisterous
I’m almost obstreperous, except for the noisy part. Perhaps it would be more accurate to say that I am obstinate or even obdurate, which mean basically the same thing.
All three words sound like they could come from the same family. In fact, obstinate comes from the Latin obstinatus, which means “resolute, inflexible, stubborn”; obsteperous comes from the Latin obstreperus, which means “clamorous”; obdurate comes from the Latin obduratus, which means “hardened.” Despite the tendency of the words to sound similar to us because of the initial ob-, that’s really just a prefix meaning “by” (former) or “against” (latter two). Otherwise, the words all have different roots. Ha ha! Latin, you’re so funny!
