Expert writing Tips

Best practice

Always use "on the third floor" instead of "at the third floor" for correct grammar. The preposition "on" is used to indicate a specific surface or level.

Common error

Avoid using "at" when referring to floors within a building. "At" typically indicates a general location or address, not a specific level.
