Expert writing Tips

Best practice

Always use the passive form "required by" instead of "require by" to ensure grammatical correctness. For example: "Submissions are required by Friday."

Common error

Avoid using "require by" in active voice constructions. The correct phrasing is almost always in the passive voice, such as "is required by" or "are required by".

Linguistic Context

The phrase "require by" functions incorrectly as it attempts to express obligation or necessity but fails to do so grammatically. Standard English requires the passive form "required by" in such contexts. As noted by Ludwig, the phrase is not standard and considered wrong.

Ludwig's WRAP-UP

The phrase "require by" is generally considered grammatically incorrect in standard English.

While the phrase appears in diverse sources, including News & Media and Science, its incorrect usage diminishes its effectiveness. Always opt for "required by" or semantically similar alternatives like "mandated by" or "stipulated by" to ensure clarity and grammatical correctness.
