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.

Hospital secrets

What is a "Code Gray" and what you should know if you hear it at the E.R.

A trip to the emergency room can be stressful enough without hearing doctors and nurses speak a language that sounds like a secret code. One minute, someone is asking for medication "STAT," the next there’s a "Code Gray," and another patient is suddenly "NPO." What do those words really mean? Some are official medical terms, others are insider slang, but they all help hospital staff communicate quickly when every second counts. Here are 10 of those codes explained.

The E.R. can be hectic and unpredictable. Most patients are frightened or uncomfortable, but now and then someone becomes aggressive because of pain, confusion, mental illness, or the effects of alcohol or other substances. That’s when you can hear "Code Gray" announced over the speakers.

The code is used to summon security officers to help manage a violent or combative situation. While color codes vary from one hospital to another, Code Gray commonly signals that staff needs extra assistance to protect patients, visitors, and healthcare workers. Even if you know it now, most people in the waiting room never know what happened, and that’s exactly the point.

You have a scheduled surgery, you’re in your bed waiting to be taken to the surgery room, and you ask for a cup of coffee to make the wait lighter. The nurse will probably tell you you’re an NPO. You may think it’s serious, but it’s simply a procedure.

"NPO" is an abbreviation that comes from the Latin phrase Nil Per Os, which means "nothing by mouth." It tells patients they cannot eat, drink, or sometimes even take medication until doctors say it’s safe. The rule is most common before surgery or certain medical tests, when food or liquids could increase the risk of complications or alter the results. It may be frustrating, but it’s an important part of keeping patients safe.

You’ve probably been through the experience of visiting an emergency room, either to get checked or to visit a loved one. In that part of the hospital where everyone is rushing to save lives, you’ve probably heard a doctor asking for the R.C.P. cart or medication "STAT!" It sounds urgent, and that's because it is.

The expression comes from the Latin statim, which means "immediately" or "without delay." Hospitals have used Latin medical terms for centuries, but STAT is one of the few that remains part of everyday conversation. When a doctor says it, the request jumps to the top of the priority list. It doesn’t always refer to a life-or-death situation, but it does mean the medical team needs something done as quickly as possible.

Newborns are always a reason to celebrate at the hospital. Parents usually rest happily next to their child as they receive congratulations from close relatives. However, the hospital is always prepared to handle extremely rare emergencies under "code pink."

If you hear a "Code Pink," it usually means a baby or young child is suspected of being abducted from the hospital. Within seconds, security officers respond, exits may be monitored or blocked, and staff begins following carefully rehearsed procedures. Although different hospitals sometimes use different color codes, Code Pink has become widely recognized across North America as one of the most serious alerts a hospital can issue.

If you’ve ever spent a few days in the hospital, you’ve probably noticed that some patients are walking up and down the halls, while others need help just getting out of bed. When a nurse refers to someone as a "walkie-talkie," it’s actually good news.

This informal expression refers to patients who can walk on their own, use the bathroom without assistance, and handle most basic tasks independently. It’s not an official medical term, of course, but it’s commonly used among healthcare workers because it quickly tells the next shift that the patient requires less hands-on care than many others.

As nurses change shifts, you’ll often hear them give a quick report about each patient. One person may only need medication, while another is described as a "total."

The term is short for a patient who requires total care. They may need help eating, bathing, getting dressed, turning in bed, or moving from one place to another. Although the expression sounds impersonal, it’s simply a practical way for caregivers to communicate how much assistance someone needs.

Most people hear "frequent flyer" and think of an airline reward program. And that’s correct, but in an emergency room, the phrase has a very different meaning.

A frequent flyer is an informal nickname for patients who repeatedly return to the hospital, often due to chronic illness, recurring medical conditions, or other ongoing health issues. Behind the light-hearted nickname is often a difficult reality. Many of these patients are simply dealing with medical problems that require regular emergency care, and the expression is just a way to make the experience a bit lighter among the familiar faces of doctors and nurses.

Not all codes are for patients. The next time you’re in a hospital, look closely at what the nurse is pushing from room to room. It may look like a small rolling desk with a computer on top. Staff often call it a "WOW," short for "workstation on wheels."

As hospitals switched from paper charts to electronic medical records, these mobile computers became essential. Nurses use them to review test results, scan medications, update patient charts, and check doctors’ orders without leaving the bedside. The name sounds funny, but the technology helps caregivers spend more time with patients instead of walking back and forth to a nursing station.

After getting a shot or having blood drawn, most patients never think about where the used needle ends up. It certainly doesn't go into an ordinary trash can.

Hospitals place needles, scalpels, and other sharp medical instruments into special containers designed to prevent accidental injuries. These sturdy, puncture-resistant boxes are sealed when full and safely disposed of in accordance with strict health regulations. This not only protects nurses, but it also protects cleaning crews, waste handlers, and even the public from dangerous needle sticks. It’s one of the most important safety measures in every hospital, even though most patients never notice it.

If you’ve ever watched a medical drama, you've probably seen a patient become so agitated that several staff members rush into the room. In situations like that, a doctor or nurse may ask for a "B-52." But the name has nothing to do with numbers themselves; it actually comes from a medicine.

B-52 is hospital slang for a fast-acting injection used to calm down patients who are severely combative or at risk of harming themselves or others. The nickname comes from a commonly used combination of medications that usually include diphenhydramine, haloperidol, and lorazepam. It’s strictly reserved for when other methods of calming the patient haven’t worked.
