Rapid increase in the number or amount of something, especially of nuclear weapons.

Carries a strong connotation of uncontrolled or undesirable spread, particularly in the context of weapons, diseases, or complex problems.

The story behind the word. The word 'proliferation' comes from the Latin 'proles,' meaning 'offspring' or 'brood,' and 'ferre,' meaning 'to bear' or 'to carry.' So, literally, it means 'to bear offspring.' The verb 'proliferate' entered English in the mid-19th century, initially in biology to describe rapid reproduction. By the mid-20th century, it gained its current widespread meaning of rapid, often undesirable, increase, especially in the context of nuclear weapons.
