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.

FAQs

Why is "ensure to" considered grammatically incorrect?

The correct form is "ensure that" or "make sure to". "Ensure" requires a "that" clause or the infinitive "to be" to function grammatically.

What are some formal alternatives to "ensure to"?

Formal alternatives include "guarantee that", "assure that", and "warrant that". These options provide a stronger sense of certainty and are suitable for professional contexts.

Is it ever acceptable to use "ensure to"?

While "ensure to" appears in some contexts, it is generally considered grammatically incorrect. It is always preferable to use "ensure that" or "make sure to" for clarity and correctness.

What's the difference between "ensure that" and "make sure to"?

"Ensure that" is generally more formal than "make sure to". While both phrases convey the same meaning of guaranteeing an outcome, "ensure that" is more appropriate for formal writing, while "make sure to" is acceptable in informal or conversational contexts.
