Meanings

Adjective

  1. determined and unwilling to give up

  2. hard to remove, shake off, or separate because it clings or persists

Beyond the definition

Think of a tiny barnacle clinging to a rock in crashing waves - that's tenacious. It describes someone or something that holds on firmly and does not give up when things get tough. A tenacious lawyer will not let go of a case until every angle has been explored, and a tenacious climber keeps going up the mountain even when exhausted.

The word comes from the Latin tenax, meaning "holding fast." It is often used to praise qualities like perseverance and resilience, but it can also describe something that is hard to remove or get rid of. Think of a weed in your garden - you pull and pull, but it just keeps coming back.
