Expert writing Tips
Best practice
When aiming to 'find something out for certain', use "ascertain" on its own, instead of the ungrammatical "ascertain to".
Common error
Don't add "to" after "ascertain". "Ascertain" already encompasses the meaning of finding something out, making the addition of "to" redundant and grammatically incorrect.
