English 'greatly' often pairs with verbs like 'appreciate', 'improve', 'vary'. In Japanese, the natural adverb depends on the verb. For example, 'greatly appreciate' is 大いに感謝する or 非常に感謝する, not 大きく感謝する. 'Greatly improved' is 大幅に改善された or 非常に向上した, not 大きく改善された (though 大きく改善された is possible in some contexts). Always check collocations.
