superlative + 'of all other'

Adding "of all other" after a superlative (best, most, least, etc.) is almost always redundant. Decide whether you mean "compared with every other item" or "compared with the remaining items after naming one" and pick the clearer form.

Below are quick checks, lots of ready-to-copy rewrites, and simple memory tricks to fix this error in work, school, and casual writing.

Quick answer

Don't add "of all other" after a superlative unless you're deliberately excluding a specifically named item and comparing the rest.

Wrong: This is the best of all other cakes I've tried.
Right: This is the best cake I've tried.
If you need exclusion: use "of the others" or "compared with the others."

Core explanation: why "of all other" is usually redundant

A superlative already signals a comparison with a group. "Of all other" repeats that idea without adding information in most sentences.

If you named one specific item and want to exclude it, say "of the others" or "compared with the others." Otherwise, prefer concise prepositions: "in the team," "among the entries," or "on the list."

Superlative alone = comparison to the relevant group by default.
"Of all other" implies excluding a named reference, which rarely applies.
Clear alternatives: "in," "among," "on," or "of the others."

How to spot it fast

Look for the pattern: [the + superlative] + [of/all/other/others]. Ask: did I explicitly name one item earlier that I want to exclude?

No named item → remove "of all other."
Yes named item and exclusion intended → use "of the others" or state the exclusion.
If the writer meant emphasis, replace with an adverb: "by far the best."

Wrong: I tasted three cakes. This is the best of all other cakes.
Right: I tasted three cakes. This is the best.

General wrong/right pairs you can copy

Default patterns: drop the extra phrase when nothing specific was named; use a short preposition or "of the others" when naming the group or excluding one item.

Wrong: That was the worst movie of all other films this year.
Right: That was the worst movie this year.
Wrong: She is the tallest of all other students in class.
Right: She is the tallest student in the class.
Wrong: This is the most expensive of all other watches I own.
Right: This is the most expensive watch I own.
Wrong: It's the fastest car of all other cars in the lot.
Right: It's the fastest car in the lot.

Work examples: professional rewrites

Business writing needs clarity and brevity. Remove the redundant phrase or specify the comparison set with a brief preposition.

Work - Wrong: Maria is the most organized of all other project managers.
Work - Right: Maria is the most organized project manager.
Work - Wrong: Q1 was the most profitable of all other quarters we've had this fiscal year.
Work - Right: Q1 was the most profitable quarter this fiscal year.
Work - Wrong: This policy is the least useful of all other policies for reducing risk.
Work - Right: This policy is the least useful for reducing risk.

Try your own sentence

Test the whole sentence, not just the phrase. Context usually makes the right choice obvious.

School examples: essays, lab reports and feedback

In academic writing, be precise. Use "in" or "among" when naming the group, and "of the others" only when you're excluding a named sample.

School - Wrong: Sample A had the highest yield of all other samples.
School - Right: Sample A had the highest yield.
School - Wrong: Her essay was the most persuasive of all other assignments submitted.
School - Right: Her essay was the most persuasive submission.
School - Wrong: This is the clearest explanation of all other student answers.
School - Right: This is the clearest explanation of the student answers.

Casual examples: reviews, posts and conversations

In casual writing or speech, tone can add emphasis. In text, prefer concise alternatives or adverbs for emphasis.

Casual - Wrong: That burger is the juiciest of all other burgers I've eaten.
Casual - Right: That burger is the juiciest I've eaten.
Casual - Wrong: She's the friendliest of all other people I met tonight.
Casual - Right: She's the friendliest person I met tonight.
Casual - Wrong: This spot has the best coffee of all other places downtown.
Casual - Right: This spot has the best coffee downtown.

Rewrite help: quick recipes and ready rewrites

Micro-checklist: (1) Find the superlative; (2) Did you name a single item to exclude? If no → remove the phrase; if yes → use "of the others" or state the exclusion; (3) For emphasis, try "by far" or "arguably."

Rewrite:
Wrong: This is the best of all other solutions we tested.
Rewrite: This is the best solution we tested.
Rewrite:
Wrong: Alpha was the fastest of all other algorithms in the benchmark.
Rewrite: Alpha was the fastest algorithm in the benchmark.
Rewrite:
Wrong: That design is the most original of all other submissions.
Rewrite: That design is the most original submission.
Rewrite (exclusion intended): Wrong: I liked Model X best of all other models. Rewrite (explicit): I liked Model X best; the other models were slower. Alternate
concise: Model X was the best.

Real usage, exceptions, memory trick, and similar mistakes

Exceptions exist for deliberate style or rhythm: "She was, of all other contestants, the most relentless." That works as rhetoric but is unnecessary in neutral prose.

Memory trick: Ask yourself, "Did I name one thing first?" If not, drop it. Simple rule: "superlative alone = fine; exclude a named item = use 'of the others.'"

Stylistic use is fine in creative writing but should be intentional.
Precise exclusion example: The red sample failed; of the others, sample B performed best.
Similar mistakes to watch: double superlatives ("most best"), incorrect comparative forms ("more better"), and awkward prepositions ("of among").

FAQ

Can I ever use "of all other" after a superlative?

Rarely. Mostly it's redundant. For exclusion, prefer "of the others" or explicitly state what you excluded.

Is "of all others" correct?

"Of all others" can be grammatical when you mean "compared with every other item," but it's often unnecessary. The shorter superlative or a clearer phrase like "among the others" is usually better.

How do I check whether removing the phrase changes meaning?

Remove the phrase and read the sentence. If the intended comparison still holds, the meaning is unchanged. If you meant to exclude a named item, name the exclusion or use "of the others."

What if I want emphasis?

Use adverbs or fixed phrases: "by far the best," "arguably the best," or "easily the most convincing." These add emphasis without redundancy.

Will grammar checkers flag this?

Many grammar tools flag redundant comparison phrases and suggest simpler alternatives. When in doubt, run the sentence through a checker or ask a colleague.

Want a quick second look?

When unsure, paste your sentence into a checker or ask: did I name an item to exclude? Removing "of all other" usually improves clarity.
