Recently, I read an article that conducted a scientific study on best selling novels. The conclusion of the tests indicated that popular books use more adjectives than adverbs and more conjunctions. In case, you need a little reminder of your English 101 class I provided definitions below.
Adverbs: Describe a verb, adjective, or other adverb.
Adjectives: Describe a noun or pronoun.
Conjunctions: Is a part of speech that connects words, phrases, sentences, and clauses.
