Ludwig's WRAP-UP
In summary, the phrase "is but" serves to diminish the importance or size of a subject, presenting it as a small component within a larger context. As Ludwig AI confirms, it is grammatically correct. It's most commonly found in formal writing across news, encyclopedic entries, and scientific documents. While phrases like "is merely" or "is simply" can serve as alternatives, they may lack the specific nuance of downplaying significance conveyed by "is but". Overusing the phrase in informal settings may sound unnatural, so it's best reserved for formal writing where its minimizing effect is most appropriate.
