A compound noun contains two or more words that join together to make a single noun, like "keyboard." A compound noun is a type of compound word that is used to designate a person, place, or thing. Compound nouns can be formed in several ways, which is one reason why writing these words can be tricky.
Examples: noun + noun bedroom water tank motorcycle printer cartridge
noun + verb rainfall haircut train-spotting
noun + adverb hanger-on passer-by
verb + noun washing machine driving licence swimming pool
When the author relates a particular event, he encourages the reader to follow along. When this happens, the reader is meant to focus on the story and understand the events that transpired. However, the reader might get distracted, or he might fail to identify the specific aspects that the author wants to highlight.
By using contrast and contradictions, the author encourages the reader to focus on a new idea that is significantly different to the one already presented. By doing so, the author forces the reader to pause, rethink and reevaluate the information presented, thus increasing his understanding of the subject.
