anticipatory comes from Latin anticipāre ('to take beforehand') + -ory, from ante- ('before') + capere ('to take'). Morphologically, the word is transparent: -ory is attached to the older base named in the history, so the modern form packages an inherited or borrowed stem inside a later English derivative. In modern use, the adjective sense is "happening in expectation of, or anticipating, a future event", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as anticipate, anticipation, anticipator and derivatives such as anticipatorily, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin anticipāre, Latin capere, which anchor the explanation in named linguistic material.
