Wenlin dictionary doesn't consider 大 as an adverb, whereas Online dictionary [Chine Nouvelle](https://chine-nouvelle.com/outils/dictionnaire.html) considers it also as an adverb.

So is 大 commonly used in modern Chinese as an adverb? Or would it not be grammatically correct to translate 大 as "greatly"?

What about the use of the structural particle 地 (de) after the adjective to make it function as an adverb concerning 大?
