Formal vs. Informal Tone

Common Mistakes
Even advanced learners sometimes confuse these words. Here are the most frequent errors:
Mistake 1: Using “decrease” as a noun when you mean “reduction”
Both are correct, but “decrease” as a noun is slightly less common in everyday speech. Example: “There was a decrease in sales” is fine, but “There was a reduction in sales” sounds more natural in business.
Mistake 2: Saying “reduce down”
This is redundant. “Reduce” already means to make smaller. Do not add “down.” Incorrect: “We need to reduce down the costs.” Correct: “We need to reduce the costs.”
Mistake 3: Using “drop” for gradual changes
“Drop” usually implies a sudden or significant fall. For slow, steady changes, use “decrease” or “fall.” Incorrect: “The population dropped slowly over ten years.” Better: “The population decreased slowly over ten years.”
Mistake 4: Confusing “increase” with “add”
“Increase” means to make larger. “Add” means to put something extra. You can add sugar without increasing the total amount if you remove something else. Example: “Add more salt” is not the same as “Increase the salt content.”
Better Alternatives and When to Use Them
Sometimes you need a more precise word than “decrease.” Here are alternatives with their best uses:
- Cut – Use for budgets, spending, or physical things. Example: “We cut our advertising budget.”
- Shrink – Use for size or volume, often in informal contexts. Example: “The sweater shrank in the wash.”
- Diminish – Use for abstract qualities like importance or influence. Example: “His role diminished after the merger.”
- Decline – Use for gradual reduction in quality, quantity, or strength. Example: “Her health declined over the winter.”
- Plummet – Use for a very fast, dramatic drop. Example: “Stock prices plummeted after the scandal.”
Mini Practice: Test Yourself
Choose the best word to complete each sentence. Answers are below.
- The company decided to _______ its prices to attract more customers. (increase / decrease / both are possible)
- After the storm, temperatures _______ to below freezing. (dropped / decreased / both are possible)
- We need to _______ the amount of sugar in this recipe. (reduce / increase / both are possible)
- His confidence _______ after he failed the exam. (diminished / increased / both are possible)
Answers
- Both are possible – The sentence works with “increase” (raise prices) or “decrease” (lower prices). Context matters.
- Both are possible – “Dropped” sounds more natural for a quick change, but “decreased” is also correct.
- Reduce – “Reduce” is the natural choice for making something smaller. “Increase” would mean the opposite.
- Diminished – “Diminished” fits the idea of losing confidence. “Increased” would mean the opposite.
