Which word best describes a person who is "elusive"?

The term "elusive" refers to someone or something that is difficult to find, catch, or understand. In the context of a person, it suggests that the individual may be elusive in their thoughts, behaviors, or presence, making them hard to pin down or comprehend fully. Therefore, the descriptor "hard to catch" aptly encapsulates this notion of being elusive. This word conveys an inherent quality of being transient or evasive, which aligns closely with the characteristics of someone who is not easily grasped, either physically or conceptually. The other options suggest traits that are contrary to the meaning of "elusive," highlighting those more straightforward, clear, or accessible qualities.
