Answer:
We hear idioms every day — both in conversation and in the media. When used correctly, idioms can amplify messages in a way that draws readers in and helps to awaken their senses. However, it’s best to avoid idioms in formal writing, because they (a) aren’t literally true; and (b) can be easily misunderstood. In formal writing, you want to be as clear, direct, and accurate as possible. The more you bring in idioms, the more likely it is that your reader will get confused and not follow your line of thought.
