Can I use "soar" and "plummet" with an adverb like "gradually"?

No, you shouldn't! Words like "soar" and "plummet" already contain the meaning of "very fast and dramatic". So saying "soared gradually" is a contradiction. Just say "soared" or "increased gradually"! 📈

It can be both! You can say "The sales plateaued in 2020" (Verb) OR "The sales reached a plateau in 2020" (Noun). Both are excellent for IELTS Writing Task 1! 📊

While technically possible in creative writing or poetry, these words are usually reserved for data, numbers, prices, and statistics. It sounds a bit unnatural to use them for emotions in daily conversation! 📝
