Synonym discussion
Sense: noun/1
All three words describe a lack of protection from negative forces, but they differ in scope and context. 'Vulnerability' is the broadest term — it can refer to physical, emotional, digital, or systemic weakness (e.g., a network's vulnerability to hackers). 'Susceptibility' adds the nuance of an internal lack of resistance rather than an external exposure: a patient can be susceptible to a virus because their immune system is weak. 'Sensitivity' focuses on the strength of reaction to a stimulus — a person with sensitive skin reacts strongly to certain chemicals, whereas someone susceptible to a disease may not react visibly at all. 'Predisposition' is the most specific: it describes a pre-existing tendency toward a particular condition, often genetic. For example: 'The doctor noted a family predisposition to diabetes' suggests inheritance, not just a moment of weakness.

Etymology
From Latin 'susceptibilis' (capable of being affected), built from 'suscipere' (to take up, receive, admit), which combines 'sub-' (meaning 'up from under') and 'capere' (meaning 'to take'). The word entered English through French in the 1600s, first describing a person's general receptiveness to impressions. The medical sense (lack of resistance to disease) developed in the 1800s. The plural noun 'susceptibilities' referring to sensitive feelings became common in the 19th century.
