Grammar is the scaffolding of clear communication. Within it, some structures are fixed—rules—and others more fluid—guidelines. While grammar rules are non-negotiable and ensure our language functions coherently, guidelines are open to interpretation and evolve with usage, tone, and context.
Breaking a rule often disrupts clarity or comprehension. But breaking a guideline can be what gives your prose its rhythm and natural tone. It’s the difference between writing by the book and writing that connects with a modern, human audience.

What Is a Grammar Rule?
Grammar rules form the core framework of how we use language. They’re the foundations that make sure communication is clear and consistent. Breaking them usually leads to confusion or sentences that sound downright wrong.
Example:
We don’t say, “He have two phone” or “She go to work every day.”
Instead, we say:
✔️ “He has two phones.”
✔️ “She goes to work every day.”
Unless you’re crafting dialogue for a character still learning the language, these rules are non-negotiable.
What Is a Grammar Guideline?
Unlike rules, grammar guidelines are more like best practices. They’re conventional, widely accepted, and often taught as “rules,” but they’re not absolute.
One well-known example is: Don’t begin a sentence with “and” or “but.”
This is not a rule—it’s a stylistic choice. Many modern writers intentionally begin sentences this way for effect.
Another classic is: Don’t end a sentence with a preposition.
Again, not a rule. It’s often more natural to say, “What are you waiting for?” rather than the overly formal “For what are you waiting?”
Why the Confusion?
There are several reasons why grammar guidelines are so often mistaken for hard-and-fast rules:
- Taught as absolutes in schools: Many teachers present guidelines as rules for simplicity, leading students to believe they’re non-negotiable.
- Reinforced by outdated textbooks: Older grammar books don’t always reflect evolving usage, keeping outdated conventions alive.
- Inherited from traditional grammar systems: Prescriptive grammar norms passed down over generations are mistaken as unbreakable.
- Echoed by armchair grammarians: Online forums, social media, and casual editors often reinforce myths without verification.
- Mimicked from formal writing: Academic and legal writing often upholds stricter standards, creating confusion for general use.
- Overgeneralization in digital tools: Grammar checkers and editing apps sometimes flag stylistic choices as errors.
- Slow pace of linguistic change acceptance: Language evolves faster than formal acceptance by educational systems and publishers.
Grammar is a collective agreement—something we’ve all bought into for mutual understanding. Still, as writing becomes more conversational and digital, what once was a “must-follow” rule may now be optional.
Grammar Guidelines Often Mistaken for Rules
Let’s unpack a few more examples of guidelines commonly confused with rules. Remember, these aren’t wrong to break—but proceed wisely.
1. Splitting Infinitives
The traditional belief is that you shouldn’t split an infinitive with an adverb. For instance, you might be told to say “to carefully read” instead of “to read carefully.”
But what about:
✔️ “She promised to always listen”?
That sounds just right. Feel free to split when it helps the sentence flow.
2. Ending Sentences with Prepositions
Instead of the awkward “From where did this come?”, it’s far more natural to write:
✔️ “Where did this come from?”
There’s no confusion, no harm, and no rule being broken.
3. Turning Nouns into Verbs
This is another guideline that stirs strong opinions. But turning a noun like “schedule” into a verb (“Let’s schedule a call”) is now common. As long as it doesn’t create redundancy or confusion, verbing a noun can keep language fresh.
However, avoid inventing verbs when a perfectly usable one already exists. No need to say “calendarise” when “schedule” works just fine.
4. Starting with Conjunctions
Traditionalists argue that you should never begin a sentence with a conjunction like “and,” “but,” or “yet.” But here’s the thing—it works.
Example:
✔️ “He said he’d arrive on time. But he didn’t show up.”
The second sentence adds emphasis. The break creates impact. That’s what good writing is all about.
5. Using Whom
“Whom” is slowly fading into grammatical history. We rarely hear anyone say, “Whom are you calling?”
It’s more natural to say:
✔️ “Who are you calling?”
Unless you’re quoting Jane Austen, feel free to let “whom” rest in peace.
6. Using “They” as a Singular Pronoun
Old-school grammar insisted on defaulting to “he” when referring to an unknown subject. But that’s exclusionary and outdated.
Instead of:
❌ “If a student wants help, he should ask.”
Use:
✔️ “If a student wants help, they should ask.”
Or better yet, go plural:
✔️ “If students want help, they should ask.”
It’s inclusive and accepted—even by many major style guides today.
To Sum Up
Follow grammar rules when clarity is at stake. Use guidelines as tools, not constraints. If a sentence reads better with a preposition at the end or a conjunction up front—go for it.
Great writing is about communication. And sometimes, breaking the rules just makes better sense.
Still unsure whether to bend a guideline or stick to the rulebook? Read your sentence aloud—if it sounds awkward or unnatural, consider revising. Always prioritise meaning and tone over mechanical perfection. And remember, your writing voice evolves with practice, so don’t be afraid to experiment with what feels right for your context and audience.
Whether you’re editing a blog, drafting a novel, or writing client copy, the real goal is to be understood—and remembered.
