What does paralyzed mean?
Paralyzed describes a person, body part, or system that has lost the ability to move or function normally, usually because of illness, injury, medication, or severe shock. It also has a well-established figurative meaning: someone can be described as paralyzed by fear, embarrassment, surprise, or confusion when unable to think or act. In this sense, the word emphasizes a temporary or psychological inability to respond rather than physical immobility. As a verb, paralyzed means to cause this loss of movement or effective action; this use is particularly natural in American English, while British English generally prefers the spelling paralysed. The word appears in both literal contexts, such as a patient with a paralyzed limb, and figurative expressions such as being paralyzed with fear. Its vivid image makes it useful for describing situations in which ordinary thought and action suddenly stop.
Unable to move or function normally; figuratively, unable to act or respond because of fear, shock, surprise, or confusion.
"The driver was found with a paralyzed left leg."
The figurative use is highly common: “paralyzed with fear” and “paralyzed by shock” are established expressions.
To cause a person, body part, or system to lose the ability to move or function normally; figuratively, to render someone unable to act or think effectively.
"The drug temporarily paralyzed his muscles."
This verb form is standard in American English; British English normally spells it paralysed.
Paralyzed comes from the same Greek roots as words meaning to loosen and release, a striking contrast to the immobility the word now describes.
