When it comes to describing something that is truly exceptional, the phrase "very great" is certainly appropriate. However, there are a plethora of synonyms that can be used to convey the same meaning with a little more nuance and specificity. For instance, "immense" and "enormous" are both descriptors that indicate a sense of size and scale. "Phenomenal," "stupendous," and "splendid" all speak to the level of impressiveness and excellence. "Magnificent" and "majestic" have connotations of royalty and grandeur. "Monumental" suggests a sense of history and significance. Finally, "extraordinary" and "remarkable" both indicate something that is truly unique and special.
