When writing a very long sentence, you must be highly descriptive by using adjectives–these are words to describe certain nouns to help a reader develop a more diverse knowledge on the word– because it can make a list longer in many ways, make people more interested in the topic, add more words to a sentence, make a sentence more valuable, interesting, logical, and sound smart, show your ability in smashing words and sentences together, and allow for more room to carry out a point, but you could also be in danger of creating sentences that are run on, and feel like they are going on forever.
