Expert writing Tips
Best practice
When using "if we knew", ensure the subsequent clause clearly outlines the alternative action or outcome that would have occurred with the presence of that knowledge. This helps create a clear conditional statement.
Common error
Avoid using "if we knew" when a more direct statement of regret or lack of foresight is appropriate. Overusing conditionals can make writing sound hesitant or unclear when a simple expression of past ignorance would suffice.
