Etymology

The word "aptitude" originates from the Latin aptitudo, derived from aptus (meaning "fit" or "suitable"). The morpheme apt retains its core sense of suitability, while itude (a suffix akin to -ity) forms abstract nouns denoting a state or condition. Over time, "aptitude" evolved in English to emphasize innate fitness or talent for specific tasks, reflecting its Latin roots in adaptability and readiness.
