Expert writing Tips
Best practice
Always use "ensure that" or "make sure to" instead of "ensure to" in formal writing. This corrects a common grammatical error.
Common error
Many writers mistakenly use "insure" when they mean "ensure". "Insure" relates to insurance, while "ensure" means to guarantee or make certain. Using "ensure" in place of "insure" is a very common mistake.

Ludwig's WRAP-UP
In summary, while the phrase "ensure to" appears frequently across diverse sources, it is considered grammatically incorrect. Ludwig AI advises using "ensure that" or "make sure to" instead. The intention behind "ensure to" is to express a guarantee or certainty, but its incorrect usage detracts from its effectiveness. Although "ensure to" can be found in scientific, news, wiki, formal and business contexts, its presence does not validate its grammatical correctness, therefore always aim for "ensure that" for formal contexts and "make sure to" for informal contexts. Stick to correct alternatives.
