What does "susceptible" imply about a person or object?

The term "susceptible" indicates a state of being open or vulnerable to certain influences, changes, or conditions. When related to a person or object, it often implies a heightened likelihood of being affected by external factors, such as diseases, emotional influences, or environmental changes. For example, someone who is susceptible to a particular illness may have an easily compromised immune system.

In this context, the word conveys a sense of weakness or lack of resilience in the face of potential challenges or dangers, which directly aligns with the meaning of "vulnerable." Other terms listed do not capture this essence—strength, fluency, and independence suggest robustness or capability, which contradicts the idea of being susceptible. Thus, "vulnerable" is the most accurate interpretation of what it means to be susceptible.
