What does paralyser mean?
A paralyser is anything that causes paralysis, especially a device, substance, or other agent that makes a person or animal unable to move. The word can also be used figuratively for a crisis, policy, or failure that brings activity to a halt. For example, severe weather may be described as a transport paralyser because it prevents trains and buses from operating, while a damaging cyberattack might become an economic paralyser by disabling essential systems. In its literal sense, the term is most often associated with medical or chemical agents, though its figurative use is prominent in news reporting and political language. The standard British and Australian spelling has an “s,” while American English uses “paralyzer.” The word is related to “paralyse,” “paralysis,” and “paralytic,” all of which ultimately derive from Greek roots meaning to loosen or disable.
A person, device, substance, or other agent that causes paralysis.
"The technician used a small electrical device as a temporary paralyser."
The literal sense is chiefly used for a device or substance that produces paralysis.
A person, event, or condition that figuratively prevents movement, action, or progress.
"The dispute became a paralyser for the entire industry."
This figurative sense is common in British, Australian, and international news language.
The plural is rarely necessary; plural usage is most natural when referring to several devices, agents, or disruptive events.
"Severe storms acted as paralysers across the region."
Sometimes the most dangerous paralyser is not a weapon but a crisis that leaves an entire system unable to move.
