Pertinacious

Definition

Stubbornly or persistently adhering to a course of action, opinion, or belief; characterized by relentless determination and refusal to yield despite opposition or difficulty. A pertinacious person holds firm convictions and won't easily be dissuaded.

Example Usage

The activist's pertinacious campaign finally succeeded after a decade of relentless advocacy.

Origin

From Latin pertinax, composed of per- (through) + tenax (holding fast, from tenere 'to hold'), meaning 'holding through' or 'holding firmly.'

Fun Fact

While pertinacious shares the positive connotation of determination, it can also imply stubborn obstinacy depending on context—the same trait viewed as admirable or annoying.
