Grammar Myths Debunked: Rules You Were Taught That Aren't Real

Discover which 'grammar rules' are actually myths — ending with prepositions, splitting infinitives, starting with and/but, and more.

For generations, students have been taught “rules” that are not actually rules of English grammar. They are style preferences, outdated conventions, or outright myths.

“Never end a sentence with a preposition."
"Never split an infinitive."
"Never start a sentence with and or but."
"Passive voice is always wrong.”

Every single one of these is a myth. This article explains why — and what the real rules are.


Rule box: Many “grammar rules” are actually style preferences or outdated conventions. The real rule: prioritise clarity, naturalness, and consistency over rigid but false rules.


The myth: You must always say “To whom did you speak?” and never “Who did you speak to?”

The truth: Ending with a preposition is perfectly natural and grammatically correct in English. The “rule” comes from Latin grammar, which doesn’t apply to English.

✅ Who did you speak to? (natural, correct)
✅ To whom did you speak? (formal, also correct)
❌ This is the sort of English up with which I will not put. (Winston Churchill’s famous mockery of the rule)

When to front the preposition: In very formal writing, fronting can sound more polished. But in most contexts, ending with a preposition is fine.

The myth: You must never put a word between to and the verb: “to boldly go” is wrong.

The truth: Split infinitives are grammatically correct and often sound more natural than the alternative.

✅ To boldly go where no one has gone before. (natural, clear)
✅ To go boldly where no one has gone before. (also correct)
❌ To go where no one has boldly gone before. (changes the meaning)

The “rule” comes from Latin, where infinitives are single words and cannot’t be split. English is not Latin.

The myth: Coordinating conjunctions must always join clauses within a sentence.

The truth: Starting a sentence with and, but, or, so, yet is perfectly acceptable in all but the most formal legal documents.

But that is not the whole story.
And so the story continues.
Yet we must not forget the lessons learned.

This “rule” has no basis in English grammar. It was invented by schoolteachers in the 19th century.

The myth: You should always use active voice. Passive voice is weak and should be avoided.

The truth: Passive voice is a useful tool. It is appropriate when the action or the recipient is more important than the doer, or when the doer is unknown.

✅ The bridge was built in 1920. (we care about the bridge, not who built it)
✅ Mistakes were made. (the doer is unknown or unimportant)
✅ The suspect was arrested by police. (standard in news reporting)

When to avoid passive: When the doer is important and you are hiding it for no reason.

❌ Mistakes were made in the report. (who made them?)
✅ The team made mistakes in the report. (clearer)

The myth: “I don’t know nothing” is always grammatically wrong.

The truth: In standard English, double negatives cancel each other out or are considered non-standard. However, in many dialects and languages (including older English), double negatives were standard for emphasis.

Standard: I don’t know anything. / I know nothing.
Non-standard: I don’t know nothing. (common in many dialects)

In exams and formal writing, avoid double negatives. But understand that this is a standardisation choice, not a universal grammar law.

The myth: None always takes a singular verb.

The truth: None can be singular or plural depending on context.

None of the students have finished. (plural — referring to multiple students)
None of the cake is left. (singular — referring to uncountable cake)


  1. Is the “rule” about Latin grammar applied to English? → It is probably a myth.
  2. Does following the “rule” make your sentence unnatural? → The “rule” is likely wrong.
  3. Is the sentence clear and natural without the “rule”? → Follow clarity, not the myth.
  4. Is it an exam? → Some myths are still tested. Know them, but know they are myths.

MythReality
Never end with preposition”Who did you speak to?” is correct
Never split infinitive”To boldly go” is correct
Never start with and/but”But wait…” is correct
Passive is always wrong”The bridge was built in 1920” is fine
None is always singular”None have finished” is also correct

Identify the myth or choose the correct option.

  1. Which is correct? (To whom did you speak? / Who did you speak to?)
  2. Which is correct? (To boldly go / To go boldly)
  3. Error spotting: Never start a sentence with but.
  4. Error spotting: The report was written by the team. (passive — is this wrong?)
  5. Fill in the blank: None of the students ___ present. (is / are)
  6. Choose: I don’t know ___ . (nothing / anything)
  7. Rewrite formally: Who are you waiting for?
  8. Which is more natural? (To really understand / To understand really)
  9. Is this correct? “And so it began.”
  10. Choose: Mistakes ___ made. (were / — )

  1. Both are correct. — ending with preposition is fine.
  2. Both are correct. — split infinitive is acceptable.
  3. Starting with “but” is correct. — it is a myth.
  4. Passive is fine here. — no need to change.
  5. are — plural noun “students.”
  6. anything — standard English avoids double negatives.
  7. For whom are you waiting? — formal preposition fronting.
  8. To really understand — split infinitive is more natural.
  9. Yes, it is correct. — starting with “and” is fine.
  10. were — passive is appropriate when doer is unknown.

Rule: Many “grammar rules” are myths. Prioritise clarity and naturalness. End with prepositions when natural. Split infinitives when clearer. Start with and/but when effective. Use passive when appropriate.

Memory trick: “Latin rules don’t bind English. Clarity beats false rules. Natural is normal.”
