anti-nuclear

The term is a modern compound, formed in the mid-20th century during the rise of the atomic age. The prefix "anti-", with ancient Greek origins meaning "against", was directly attached to the adjective "nuclear", which itself derives from the Latin nucleus (a kernel or core). "Nuclear" evolved from its general biological meaning to specifically denote the core of an atom following advancements in physics. Thus, "anti-nuclear" literally constructs the meaning "against that which pertains to the atomic nucleus," capturing opposition to the technologies derived from atomic energy.

Structure: anti (against) + nuclear (relating to atomic nuclei) - anti: From Greek via Latin, meaning "against" or "opposite". It functions as a prefix indicating opposition. - nuclear: From Latin nucleus (kernel, central part) + English adjectival suffix -ar. It functions as the root adjective describing something related to the nucleus of an atom.
