Here's why:
* Elusive: Means difficult to find, catch, or achieve. It suggests something that is hard to pin down or grasp.
* Cautious: Means careful, wary, and avoiding unnecessary risks. It suggests someone who is thoughtful and deliberate in their actions.
While they might seem opposite in a way, they're not true antonyms.
Here's an example:
* Elusive: The thief was elusive, disappearing into the crowd before the police could catch him.
* Cautious: The cautious hiker carefully checked the trail for any signs of danger before proceeding.
An antonym for "cautious" might be:
* Reckless
* Careless
* Rash
* Impetuous
