anti-depressant

The word 'antidepressant' is a modern scientific compound built from classical roots. The core 'depress' originates from the Latin deprimere ("to press down"), a combination of de- ("down") and premere ("to press"), which metaphorically evolved to describe low spirits or melancholy. The prefix 'anti-', from Greek, directly means "against" or "opposing". The suffix '-ant' indicates an agent or substance. Thus, the literal construction "a substance that works against (the state of being) pressed down" perfectly captures its function in countering the psychological condition of depression.

Structure: anti (against) + depress (press down) + ant (agent/thing) - anti: From Greek anti, meaning "against, opposite". - depress: From Latin depressus, past participle of deprimere, meaning "to press down". - ant: A suffix of Latin origin (-antem, accusative of -ans), forming agent nouns or adjectives, here meaning "a substance or agent that performs an action".
