"Bestest" is a playful, nonstandard form created by adding -est to an already superlative word: best. It works as a casual or childlike expression, but it's incorrect in standard English.
Quick answer
"Bestest" is nonstandard. Replace it with "best" or another precise phrasing in formal or neutral writing; reserve "bestest" for intentional, playful tone.
- Formal/work/school: use "best" or a specific alternative (e.g., "the best candidate," "one of my closest friends").
- Casual/affectionate: people will understand "bestest," but it remains nonstandard.
- For extra emphasis, prefer "the very best," "truly the best," or "one of the very best."
Core explanation - why "bestest" is incorrect
"Best" is already the superlative of "good": good → better → best. Adding -est to an already superlative word duplicates the marker and creates a nonstandard form.
Think of "best" as a final form: you don't stack superlative markers on it.
- Irregular: good → better → best (no -est after best).
- Don't write: bestest, mostest, goodest.
- Wrong: She is my bestest friend.
- Right: She is my best friend.
Superlative grammar notes - fast rules you can use now
One-syllable adjectives usually take -er / -est (tall → taller → tallest). Two-syllable and longer adjectives use more / most (careful → more careful → most careful). Irregular forms must be memorized (good → better → best).
- Rule of thumb: if the base word already means "the top," don't add -est.
- Use "most" for long adjectives (most interesting), not "-est."
- Wrong: This is the mostest interesting chapter.
- Right: This is the most interesting chapter.
- Wrong: He's the goodest player.
- Right: He's the best player.
Hyphenation and spacing notes
Adding a hyphen or a space doesn't make a nonstandard form correct. "Best-est" or "best est" are still playful spellings, not standard grammar.
Use hyphens for true compound modifiers (well-known author), not to "fix" a wrong superlative.
- Don't write: best-est, best est - they remain nonstandard.
- Acceptable as intentional styling on novelty items, but avoid in prose.
- Usage: Novelty mug: "World's Best-est Mom" (stylistic).
- Rewrite: Email signature: use "Best regards" not "Bestest regards."
Small change, big impression
Fixing "bestest" is a tiny edit that improves clarity and credibility. It signals care about tone and accuracy without changing your voice.
If you write often, a grammar assistant will flag recurring slips like "bestest" and suggest standard rewrites while keeping your intended tone.
Real usage and tone - when people actually say "bestest"
"Bestest" appears in children's speech, playful texts, memes, and intentionally comic writing. Use it only when the audience expects a casual or childlike voice.
Avoid it in resumes, academic work, client emails, or anything that should read as professional or objective.
- Acceptable uses: notes from a child, joking messages among close friends, novelty gifts.
- Avoid in: academic essays, business communications, formal letters, public-facing content.
- Usage: Text to a close friend: "You're the bestest!" (affectionate, casual)
- Usage: Child's card: "To my bestest Grandma" (childlike voice)
- Do not use in: "Attached is the bestest proposal" (client email - unprofessional)
