Nothing is set in stone
The Oxford comma is a choice, not a rule (and it is not about grammar)
Published on June 16, 2026
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.
Sentences should never end in a preposition
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.
You should never split an infinitive
‘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.
You should always use ‘whom’ when referring to the object
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’.
Sentences should never start with conjunctions
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 Oxford comma is mandatory
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.
Adjectives should always precede the noun they modify
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.
The subjunctive is mandatory for conditions uncertain or contrary to fact
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.
‘They’, ‘their’, and ‘them’ should only be used for plural antecedents
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.
A double negative will always be understood as positive
"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.
‘None’ should always be followed by a singular verb
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.
