Expert writing Tips

Best practice

When describing a reduction, use "a significant decrease" instead of the grammatically incorrect "a significantly decrease". Ensure the adjective form "significant" modifies the noun "decrease".

Common error

Avoid using the adverb "significantly" directly before the noun "decrease". Adverbs modify verbs, adjectives, or other adverbs, not nouns. Use the adjective "significant" instead to correctly modify the noun.
