Nothing is set in stone

The Oxford comma is a choice, not a rule (and it is not about grammar)

Unlike languages like French or Spanish, the English language does not have an official academy that registers the use of the language and determines which rules still apply and which are obsolete. While institutions such as the Oxford Dictionary help with standardizing and registering the language, English evolves through the daily use of its speakers, and its rules evolve with it.

As a consequence, some rules are more fixed than others, and many of them are not so much rules as they are stylistic choices. Does this mean we can write however we please? Not exactly, but it means that many "rules" are not set in stone. Let’s see some language mandates that are more of a guideline.

As evidenced by daily language, it is perfectly acceptable to end a sentence with a preposition, no matter the context or the formality. In fact, it’s something that speakers tend to do naturally. The idea that ending sentences with a preposition is incorrect is a myth left over by 17th-century grammarians trying to impose Latin grammar on the English language.

‘To run quietly’ or ‘To quietly run’, which one is correct? The answer is both. The choice to place an adverb after the infinitive or in the middle of it has nothing to do with proper grammar, but with emphasis and sounding more natural. Again, this "rule" is a leftover from Latin grammar.

Not so long ago, this rule was set in stone, and saying "to who?" instead of "to whom" would get you a few stares. However, rules change as people change, and the use of ‘who’ to refer to the object has become increasingly more common. However, this only applies to informal contexts. In a more formal setting, it is recommended to still use ‘whom’.

Much like prepositions at the end of sentences, conjunctions —such as and, but, so, or, nor, for, and yet— can go at the beginning of a sentence. This helps with emphasis, breaks up long sentences, and provides flexibility, although it is recommended to use them sparingly in this way.

The first issue here is that the serial comma, better known as the Oxford comma, is a punctuation issue, not a grammar rule. That aside, although it is recommended to avoid confusion caused by lengthy enumerations, in the end, it is a stylistic choice, and it is only considered mandatory in contexts that follow a certain style guide.

Just because in most cases the adjective goes before the noun, it does not mean it should always do so. English speakers tend to naturally put the adjective first when talking about qualities and characteristics, but in many cases, putting the noun first will sound better. Again, it depends on your preferences and the flow of the sentence.

While this is technically correct and subjunctive has been used this way for centuries, this rule mainly applies to written language and formal contexts. In colloquial English, speakers tend to use both the indicative and the subjunctive for uncertain or contrary-to-fact scenarios, such as saying "If I was you" and "If I were you". The choice almost always boils down to what sounds more natural.

Once an unbreakable rule, the use of ‘they’, ‘their’, and ‘them’ for a singular antecedent is widely accepted nowadays, even in the most formal contexts, to fill the gap left by the lack of gender neutral pronouns. In fact, many style guides recommend using these words as singular to avoid awkwardness and assuming someone’s gender.

"Two negatives make a positive", a rule you must have heard about in school. While this is a fact in math, it is not always true in grammar. In more standard English variants, the rule applies, especially in academic writing and formal contexts. However, informal dialects and vernaculars follow the ‘negative concord’: here, the second negative intensifies the first one instead of cancelling it.

This is a myth made popular by old grammar books. ‘None’ can be used with both singular and plural verbs, depending on the meaning. When ‘none’ is used to mean ‘not any’, it is more natural to use a plural verb. When it means ‘not one’ or ‘not any of it’, the verb should be in the singular form. If you are unsure, pick the choice that sounds clearer and more natural.

Behind popular wisdom

12 common sayings that don’t mean what you think

We hear them daily and rarely question their meaning, but many popular sayings come from surprising origins—or mean something entirely different than we think. Some of these discrepancies are rooted in history, others in mistranslation, and more than a few in good old-fashioned misunderstanding. Here are 12 familiar phrases decoded and laid bare with real facts.

The original version, a 12th-century German proverb—_"The blood of the covenant is thicker than the water of the womb"_—suggests chosen bonds (like friendship or military brotherhood) are stronger than family ties, the opposite of how it’s used today. This shift in meaning likely occurred in later times, as the abbreviated form entered popular speech.

The full phrase is "Great minds think alike… and fools seldom differ." With the full version, the meaning turns ironic—it suggests that both geniuses and fools can agree just as easily, likely a warning against groupthink.

This proverb is often used to warn against dangerous inquisitiveness, but the full version—_"Curiosity killed the cat, but satisfaction brought it back"_—adds nuance. It suggests that the reward of knowing can outweigh the risks of curiosity.

The full phrase is "Jack of all trades, master of none, but oftentimes better than master of one." Originally, it praised versatility, not criticized it. The missing line completely flips the meaning, suggesting it’s often better to be well-rounded than narrowly skilled.

This phrase meant an impossible task—just like lifting yourself by your own shoelaces. First recorded in the 1800s, it mocked absurd self-starting efforts. But by the 20th century, American individualism had flipped its meaning into a motivational mantra.

The original phrase is "The proof of the pudding is in the eating," meaning you have to try something to know if it’s good. The modern shorthand makes little sense by itself and loses clarity but still hints at the original idea: results matter more than appearances.

There are competing theories about this phrase’s origin. The most common links it to boxing radio commentary, where a losing fighter is "saved by the bell" at the end of a round. Others trace it to 18th-century burial customs, when the fear of being buried alive led to coffins being rigged with strings tied to bells aboveground.

A popular myth claims the phrase "rule of thumb" stems from a law allowing men to beat their wives with sticks no thicker than a thumb. Fortunately, no such law ever existed. The phrase dates back to the 17th century and likely originated in trades where measurements were estimated using the thumb’s width or length.

One theory about the origin of "cold turkey" links it to the clammy, pale skin that some people experience during withdrawal, said to resemble cold turkey meat. However, a more likely explanation is that it combines the earlier idiom "talking turkey" (meaning to speak plainly) with "cold," used to describe something abrupt or blunt.

This phrase isn’t about feeling cozy—it refers to rope-strung beds from the 18th century. Back then, mattresses rested on a web of ropes that needed regular tightening. "Tight" meant the ropes were pulled firm to prevent the mattress from sagging.

Though it sounds mythological, this phrase comes from early 1700s theater. Playwright John Dennis invented a new thunder sound effect for his play. After the show flopped, another theater used the effect without credit. Dennis famously complained, "They will not let my play run, but they steal my thunder."

Before modern transportation, trade ships often got stuck in winter ice. So, smaller vessels were sent to break the ice and clear a path. Used since at least the 16th century, the original nautical context made it a natural metaphor for overcoming barriers.
