The Origin of Inactivate or Deactivate

Deactivate comes from the prefix de- (meaning “down” or “away”) and activate (to make active). It entered common English in the 19th century and became popular with machines and later digital systems.

Inactivate comes from the prefix in- (meaning “not”) and active. It has roots in scientific and medical writing, where it often means neutralizing or disabling something at a functional level.

There is no spelling difference due to region. The difference exists because of usage and context, not British or American spelling rules.
