Relating to opposition against nuclear weapons or nuclear energy.
The antinuke movement advocates for the reduction of nuclear arms worldwide.
Antinuke is formed from "anti-" (meaning against) and "nuke" (derived from the slang term for nuclear, which comes from the Latin "nucleus", meaning core or center). The word antinuke refers to a stance or movement that is against nuclear weapons or nuclear energy.
Think of 'anti-' meaning against, and 'nuke' referring to nuclear energy or weapons. This helps you remember that antinuke means being against nuclear power or weapons.
