The word "projection" originates from Latin proiectio, derived from proicere ("to throw forward"), combining pro- (forward) and iacere (to throw). The root ject (from iacere) appears in many English words (e.g., "eject," "inject"). Over time, "projection" evolved from its literal sense of "throwing forward" to abstract meanings like mental transfer ("psychological projection") and geometric representation ("map projection"). The suffix -ion nominalizes the action, making it a concrete concept.
