Expert writing Tips
Best practice
Omit "down" to avoid redundancy: use "decreases to" instead of "decreases down to" for more concise and grammatically correct writing.
Common error
Don't use both "decreases" and "down to" together. The word "decreases" already indicates a downward direction, so "down to" is unnecessary and makes the sentence less clear. For example, prefer "The temperature decreases to 10 degrees" over "The temperature decreases down to 10 degrees."
