Expert writing Tips

Best practice

Avoid using the phrase "at overnight". Instead, opt for clearer alternatives like "by morning" or "during the night" to improve grammatical accuracy and readability.

Common error

Don't use "at overnight" as if 'overnight' is a specific time. Remember 'overnight' typically functions as an adjective or adverb, not as a noun that takes a preposition. Instead of saying, 'the reaction was stirred at overnight', say 'the reaction was stirred overnight'.
