When we think of the phrase "shoots up," it often conjures images of growth and progress. However, there are plenty of antonyms for this phrase that connote the opposite. Words such as "decline," "slump," and "plummet" all paint a different picture of the situation.
While shooting up may imply success and prosperity, these antonyms illustrate a situation where things are looking bleak. When a market is declining or a business is slumping, we see the opposite of growth and progress.
It's important to be aware of these different connotations when using language. Sometimes, even slight variations in word choice can completely change the tone of a message.
