Expert writing Tips

Best practice

In technical writing, distinguish between validity (structural correctness) and truth (actual factual accuracy) depending on your field.

Common error

In formal logic, an argument can "Be valid" even if its premises are false, as long as the conclusion follows logically from them. Do not use "Be valid" as a synonym for "be true" in rigorous academic or scientific writing without clarifying your intent.

Ludwig's WRAP-UP

In summary, "Be valid" is a highly versatile and correct construction used to denote legitimacy and logical soundness. Ludwig shows that it is exceptionally common in authoritative spheres such as news media, scientific research, and academic law. Whether you are discussing the duration of a ticket or the integrity of a scientific theory, this phrase serves as a precise tool for verification.
