Meanings of Susceptible
Susceptible means being easily affected, influenced, or impaired by something. The word can describe physical vulnerability (for example, to disease), emotional openness (such as being easily moved by praise or criticism), or cognitive sensitivity (such as being influenced by persuasive ideas or suggestion). In many cases, it helps to think of susceptible as a combination of responsiveness and risk.
Definition
Susceptible refers to the condition of being likely or prone to be affected by an external factor. When someone is described as susceptible, the context often determines the tone: emotionally, a person may be susceptible to flattery, manipulation, or peer pressure, which can make them more easily persuaded. In scientific or technical writing, the word commonly signals measurable responsiveness—such as susceptibility to a virus, a force, or a stimulus. The term is often neutral in meaning, but it can imply limited resistance or fragility depending on how it’s used.
Etymology
The word susceptible comes from the Late Latin susceptibilis, derived from suscipere, meaning “to take up, sustain, or receive.” Its Latin roots include sub- (“up from below”) and capere (“to take”). The term entered English in the early 1600s, initially referring to capacity or receptiveness. Over time, it gained more specific uses in areas such as medicine and psychology. Today, “susceptible” keeps that core idea of openness—whether to illness, emotion, or external factors—while also emphasizing risk and responsiveness in context.
