Expert writing Tips

Best practice

When aiming for clarity, replace "know you understood" with grammatically correct alternatives such as "know that you understood" or "confirm you understood".

Common error

Avoid omitting the conjunction "that" after "know" when expressing a complete thought. Saying "know you understood" sounds fragmented. Instead, use "know that you understood" to create a clear and grammatically sound statement.
