Etymology: The root of "incapacitor" is the Latin verb "capere," meaning "to take" or "to hold." A "capax" was something able to hold a lot, so "capacity" originally meant room to contain something. Adding the negative prefix "in-" gives "incapax," unable to hold or to do. The English verb "incapacitate" comes from Medieval Latin "incapacitare," which took that sense of lacking capability and gave it a verb form. The ending "-or" marks the thing that performs the action, as in "generator" or "reactor," so an incapacitor is literally whatever makes something unable. Because the same root gives "capacity," this word shares its ancestry with terms about containing and holding, even though its sense runs the other way.
