an adverb is a word used to modify a verb, an adjective, another adverb, a phrase, or a clause. They indicate manner, time, place, degree, and frequency. 'Incredibly' is used to represent an intensity of degree, implying 'very' or 'unbelievably'.
generally, the adverb 'incredibly' is placed directly before the word it is modifying. As such, the word can be used in any context to add emphasis to a verb, adjective, or adverb.
1. I was incredibly frightened by the news.
2. She ran incredibly fast.
3. He answered incredibly quickly.
the adverb 'incredibly' should not be used to modify nouns. Additionally, 'incredibly' should not be preceded by an adverb of degree, such as 'very' or 'extremely', as this would make the sentence redundant.
