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.

Facts you didn't know you needed

Is the day longer for your pet? Mind-blowing facts you need to know

Adults often assume they already understand the world, but there’s always something new to surprise us! Did you know that clouds actually have weight? Or that the day is longer for some animals? And that’s just the beginning. From hidden functions of your organs to the true color of the universe, today you’ll learn 10 fascinating facts you probably never thought to ask, but will make you sound impressively smart in your next conversation!

Unlike humans, animals don’t experience a shared "present" in quite the same way. Instead, their sense of time is tied to the rhythms of their own bodies. For very small animals with fast metabolisms like parrots, hamsters, or guinea pigs, time actually seems to pass more slowly. In a sense, they live in slow motion because their faster-working nervous systems allow them to process sensory information at a fast speed.

What if someone commits a crime and tries to blame their identical twin? Have you ever wondered about that? It’s a valid question; after all, identical twins not only look alike, they also share the same DNA. But here’s the surprising part: if investigators check fingerprints, the innocent twin could be cleared. That’s because, despite their nearly identical DNA, twins have unique fingerprints, shaped by subtle genetic and environmental factors in the womb.

You’ve probably spent time lying on the grass, watching clouds drift across the sky. They look light, fluffy, almost like cotton candy, and it’s hard to imagine them as heavy objects. But the truth is surprising: clouds are incredibly heavy. An average cumulus cloud can weigh around 1 million pounds! That impressive weight comes from the billions of tiny water droplets suspended in the air. So, how do they float? It’s because each droplet is extremely small and falls very slowly, while rising warm air currents help keep the cloud suspended above us.

Most of us have a rough image of the world map in our minds. But we have something to tell you: most maps aren’t completely accurate. Because the Earth is a sphere, cartographers have to distort some areas to represent it on a flat surface. On Mercator projection maps, countries near the poles appear much larger than they really are, while countries near the equator look smaller in comparison. For example, Alaska looks about the same size as Brazil, but in reality, Brazil is nearly five times larger!

Most people don’t realize that there’s actually a name for the color of the universe. Strange, right? But it’s true! Astronomers who studied the light from thousands of galaxies discovered that if you blend all the colors from the observable universe, the result is a soft, beige-ish white shade, famously named "Cosmic Latte" in 2002.

With 50 states, there’s no shortage of variety in their names. Almost every letter of the English alphabet appears at least once, except for one: Q, which is completely absent. In addition to this, there’s another surprisingly rare letter: J. While it isn’t entirely missing like Q, it only appears in one state, New Jersey.

Although we don’t notice it, indeed, the Earth’s rotation is gradually slowing. This happens because tidal friction, caused by the Moon’s gravitational pull on our oceans, creates a subtle drag on the planet’s spin. As a result, days are getting longer, but very gradually: by only about 1.7 milliseconds per century.

Do you remember your last dream? Whether good or bad, dreams are a constant part of sleep, but not everyone experiences them in the same way. Deaf people who use sign language in their daily lives often communicate through signs in their dreams, too. Meanwhile, blind people tend to have dreams rich in sounds, smells, and tactile sensations, using these other senses to experience the dream world.

We’re used to seeing hippos covered in mud, splashing in water, or barely peeking above the surface. But here’s a surprise: hippos can’t actually swim! That’s right. Because of their huge, heavy bodies, they don’t float or paddle like most animals. Instead, they walk or run along the riverbed.

Can your brain really "eat" itself? Well, close, but not exactly. There’s a process called phagocytosis, carried out by specialized immune cells in the brain known as microglia. These cells engulf and remove debris, dead cells, and other unwanted material. But don’t worry; it’s safe! The mechanisms exist to protect, repair, and maintain your brain.
