means The crime of seizing and carrying off a person by force or deception, typically to extort ransom or for some other unlawful purpose.

from A 17th-century English compound of 'kid' (a slang term for a child, borrowed from the young of a goat) and 'nap' (a variant of 'nab,' meaning to snatch or grab). It first described the snatching of children and young people to be shipped off as servants and laborers to the American colonies — only later did the word stretch to cover the abduction of anyone, of any age.
