A more thorough explanation:

Definition: Susceptibility refers to the condition of being subject, exposed, or liable to something. It can also mean the act of subjecting someone to something or the condition of a subject in a monarchy.

Examples:

• Due to his weakened immune system, he had a high susceptibility to infections.
• The subjection of prisoners to inhumane treatment is a violation of human rights.
• As a subject of the kingdom, he owed loyalty and obedience to the monarch.

The first example illustrates susceptibility as a condition of being exposed or liable to something, in this case, infections. The second example shows susceptibility as the act of subjecting someone to something, in this case, inhumane treatment. The third example demonstrates susceptibility as the condition of a subject in a monarchy, with the subject owing loyalty and obedience to the monarch.
