Both "quietest" and "most quiet" are grammatically correct, though "quietest" is significantly more common and generally preferred in modern English.
Understanding Adjective Superlatives
Adjectives change their form to show degrees of comparison. For the highest degree, known as the superlative, we describe something as having the quality to the greatest extent.
General Rules for Superlatives
- One-syllable adjectives: Typically add "-est" (e.g., tall, tallest; fast, fastest).
- Three or more syllable adjectives: Typically use "most" before the adjective (e.g., beautiful, most beautiful; intelligent, most intelligent).
- Two-syllable adjectives: This category is more flexible. Some two-syllable adjectives always use "most" (e.g., famous, most famous), while others can use either "-est" or "most."
The Case of "Quiet"
"Quiet" is a two-syllable adjective, which places it in the flexible category. While the "rule-of-thumb" for some two-syllable adjectives might suggest "most quiet" as the expected form, common usage strongly favors "quietest."
- Preference: "Quietest" is approximately six times more common in everyday usage than "most quiet." This widespread adoption makes "quietest" sound more natural and expected to most English speakers, particularly in American English.
- Correctness: Despite the strong preference, both "quietest" and "most quiet" are considered grammatically correct. You will encounter both forms, but the single-word construction is the prevalent choice.
Examples in Context
Here are examples demonstrating both forms:
- Using "Quietest" (Preferred)
- "The library is the quietest place in the entire building."
- "Among all the siblings, she was the quietest during dinner."
- Using "Most Quiet" (Correct, but Less Common)
- "For deep concentration, that secluded corner is the most quiet spot."
- "The baby was the most quiet I had ever seen her."

Why the Preference for "Quietest"?
Language is dynamic, and common usage often shapes what becomes standard. For "quiet," the shorter, single-word comparative ("quieter") and superlative ("quietest") forms have simply become the established and expected constructions over time. This makes them flow more naturally in speech and writing for many native speakers. For more information on adjective forms, you can refer to reputable grammar resources or dictionaries like Merriam-Webster.
