anti-aids

The word is a modern scientific compound formed in the late 20th century. The prefix "anti-," of ancient Greek origin meaning "against," is directly attached to the acronym "AIDS," which names the disease syndrome. This follows a productive pattern in English where "anti-" is prefixed to nouns to form adjectives describing opposition or prophylaxis (e.g., anti-malarial, anti-bacterial). The literal construction "against-AIDS" transparently conveys the word's function, describing agents, measures, or research aimed at countering the disease.

Structure: anti (against) + aids (disease) - anti: From Greek, via Latin and French. A prefix meaning "against," "opposite of," or "preventative of." - aids: An acronym for "Acquired Immune Deficiency Syndrome," the name of the specific disease.
