What is the comparative form of proudly?

There is no comparative form of "proudly" because it is an adverb. Adverbs describe verbs, adjectives, or other adverbs, and they don't have comparative or superlative forms like adjectives do.

If you want to express a higher degree of pride, you would use a different word or phrase, such as:

* More proudly

* With greater pride

* With more pride

* Most proudly

* With the greatest pride

For example:

* "He walked proudly down the street."

* "He walked more proudly than ever before."

* "He walked with greater pride after winning the award."
