The word "intercourse" originates from Latin intercursus, combining inter- (between) and cursus (a running, course). Initially, it referred to any form of interaction or exchange, such as trade or conversation. Over time, its meaning narrowed in English to emphasize social or sexual interaction, reflecting the metaphorical "flow" of connection between parties. The root course retains its sense of movement (e.g., "watercourse"), while inter- consistently denotes reciprocity.
