Differences between American and British writing

So let’s dive in and unravel the unique variations between these two fascinating flavors of our shared English language!

Historical Context of American and British English

The English language originated from several dialects, now collectively termed Old English, which were brought to the eastern coast of Great Britain by Anglo-Saxon settlers in the 5th century. This Germanic language was influenced by Latin, Celtic, and Norse languages throughout the Middle Ages. The language evolved into Middle English around the 12th century, largely due to the influence of the Norman Conquest.

By the late 15th century, Modern English emerged with the printing press invention by Johannes Gutenberg and the London dialect’s standardization. During the British colonization, English spread worldwide, leading to various forms, including American and British English.

Over time, variations in vocabulary, spelling, grammar, and pronunciation developed between the English spoken and written in England versus North America. The geographical difference meant new terms and slang could develop without immediately spreading across the ocean.

The Origins of American English

American English has its roots in the 17th century when British colonization of the Americas began. The first wave of English-speaking settlers, primarily Puritans and other religious dissenters, established the original thirteen colonies along the eastern seaboard of the United States.

These colonists brought the English language as it was spoken and written in England then. However, as they encountered new landscapes, animals, plants, and cultures, they began to develop new words to describe their experiences. Additionally, they borrowed words from Native American languages, Spanish, Dutch, and French, further expanding and diversifying the vocabulary of American English.

The next significant influence on American English came with the arrival of Noah Webster in the late 18th and early 19th centuries. Webster, a lexicographer, grammarian, and language reformer, is often called the “Father of American English.” He believed American English should be distinct from British English, reflecting the young nation’s independence from Britain.

Webster introduced several spelling reforms in his dictionary, many of which are still used today. These include dropping the ‘u’ in words like ‘colour’ to become ‘color,’ changing ‘re’ to ‘er’ in words like ‘centre’ to become ‘center,’ and replacing ‘ce’ with ‘se’ in words like ‘defence’ to become ‘defense.’ His reforms were not universally accepted initially but gradually became standard in American English.

In the 19th and 20th centuries, waves of immigrants worldwide influenced American English, introducing new words and accents. Today, American English continues to evolve, reflecting the country’s diversity and dynamism.

The development of American English is thus a story of adaptation and change, influenced by historical events, cultural shifts, and the constant influx of new ideas and people. It stands as a testament to the dynamic nature of language and its capacity to evolve.

While American and British English remain mutually intelligible, their distinct vocabularies, spellings, grammar conventions and stylistic preferences continue to set them apart today.

Spelling Differences

There are many common spelling differences between American and British English. Here are some key examples of words spelled differently in each variant:

Missing “U” in American English

One of the most noticeable spelling differences is that certain words containing “U” in British English are spelled without the “U” in American English. Some examples include words like “colour” (color), “favourite” (favorite), “humour” (humor), “labour” (labor), and “neighbour” (neighbor).

Different Endings (“-Re” vs “-Er”)

Some words end with “-re” in British English but take “-er” in American English. These include words like “centre” (center), “fibre” (fiber), “metre” (meter), “theatre” (theater), and “spectre” (specter).

Different Spellings of “-Ise” and “-Yse”

Verbs that end in “-ise” in British English are usually spelled “-ize” in American English. Examples: “organise” (organize), “recognise” (recognize). Similarly, nouns ending in “-yse” in British English take “-yze” in American spelling. For instance, “analyse” (analyze), “catalyse” (catalyze).

Different Doubling of Consonants

Some words have double consonants in British English but single consonants in American English. These include “traveller” (traveler), “counsellor” (counselor), “skilful” (skillful), and “wilful” (willful). The opposite is also true for some words like “worshiping” (worshipping) and “kidnaped” (kidnapped).

Awareness of these spelling conventions can help avoid confusion when writing for different English-speaking audiences. The key is to be consistent within a single piece of writing and use the variant your target readers expect.

Vocabulary and Terminology Differences

American and British English may be the same language, but they have evolved differently, leading to notable differences in vocabulary and terminology. Here are some examples of how everyday words and phrases differ on each side of the Atlantic:


  • British English uses “lorry,” whereas American English uses “truck”
  • “Boot” (British) vs. “trunk” (American) – the storage area of a car
  • “Bonnet” (British) vs. “hood” (American) – the covering over a car’s engine

Food and Drink

  • “Chips” in British English refers to thick-cut fries, while “crisps” are potato chips. In American English, “chips” are potato chips.
  • “Biscuit” (British) vs. “cookie” (American) – a small, baked, sweet treat
  • “Aubergine” (British) vs. “eggplant” (American) – the purple vegetable

Housing/Household Items

  • British English uses “flat,” whereas American English uses “apartment”
  • “Lift” (British) vs. “elevator” (American) – a mechanism for moving between floors in a building
  • “Torch” (British) vs. “flashlight” (American) – a portable battery-powered light

A British reader may be confused to read about “cookies” and “eggplants,” just as an American reader may stumble over “biscuits” and “aubergines.” Writers aiming for clear communication across dialects should be mindful of these subtle differences.

Grammar and Punctuation Differences

American and British English have several key differences in grammar and punctuation. While American English was heavily influenced by Webster’s push for spelling reform in the 19th century, British English retained more traditional grammar rules. Let’s explore some main ways grammar and punctuation vary between the two dialects.

Verb Usage and Conjugation

One area where American and British English differ is in verb usage and conjugation. Some examples:

  • The past tense of the verb “to learn” is “learned” in American English but “learnt” in British English.
  • American English uses the past tense “dove,” whereas British English uses “dived” for the past tense of “dive.”
  • The past participle of “to get” is “gotten” in American English but “got” in British English.

Many other verbs follow different rules in American vs. British English. These variations developed over time as the dialects diverged.

Collective Nouns

British and American English treat collective nouns (group nouns) differently regarding verb conjugation. American English considers collective nouns as singular entities and uses a singular verb. British English treats the noun as plural and uses a plural verb.

Let’s see some examples:

  • American English: The team is doing well this season.
  • British English: The team are doing well this season.


Punctuation rules also differ between the variants:

  • American English puts punctuation within quotation marks, while British English puts punctuation outside, with some exceptions.
  • British English tends to use more commas before conjunctions in sentences.
  • American English favors the serial comma (before “and” in lists), while British English usually omits it.

These punctuation differences developed over time through convention and can impact the cadence of sentences.


In certain variants, some prepositions are preferred over others:

  • British English says “at the weekend,” while American English says “on the weekend.”
  • British English uses “in hospital” vs. “in the hospital” in American English.
  • American English says “on campus,” while British English says “at university.”

Many subtle preposition differences can identify someone’s regional background.

In summary, grammar and punctuation diverged noticeably between American and British English over the centuries. Writers and editors should be aware of these differences for their target audiences. With some study and practice, these variations can be easily mastered.

Stylistic Differences

American and British English have diverged over time into distinct stylistic variants. While the core grammar remains largely the same, there are subtle differences in formal versus informal language and the prevailing tones and attitudes conveyed through writing.

Use of Formal and Informal Language

British English tends to be more formal and reserved compared to American English. For example, British writers are likelier to use ‘one’ instead of ‘you’ to maintain formality and distance.

Americans tend to be more direct, using contractions like ‘can’t’ and ‘won’t’ even in formal writing, while British writers avoid contractions in formal contexts. American English also has more slang and colloquialisms in everyday use.

Differences in Tone and Attitude

The tone of British English often comes across as detached and objective compared to American English. British writers are more reserved and understated, whereas Americans adopt a more open, straightforward tone.

For instance, American writers are likelier to use intensifiers like ‘very’ or ‘really,’ whereas British writers prefer to make their point indirectly. Additionally, there are also differences in expressing politeness. Americans value directness, whereas the British emphasize formality and indirectness to maintain politeness.

These stylistic divergences stem from broader cultural attitudes and values. Understanding these differences can help writers adapt their style appropriately for each audience. With globalization, there is also more blending between American and British stylistic conventions. However, being aware of the key differences remains important for effective cross-cultural communication.

Impact on Communication and Writing

The differences between American and British English can lead to misunderstandings and confusion in international communication.

Though the two variants largely resemble each other, the spelling, vocabulary, grammar, and style discrepancies can impede effective cross-cultural written correspondence. Being cognizant of these divergences enables clearer communication and avoids potential offense.

For example, an American spelling the word ‘color’ and a British spelling ‘colour’ may appear to be an error to the other group. Utilizing certain slang words recognized in one area but not the other can completely obscure the intended meaning.

Grammar rules around collective nouns, subject-verb agreement, or serial commas vary across the variants too. Even stylistic choices like using contractions more liberally (Americans) versus proper form (British) shape perceptions.

These distinctions matter for businesses operating internationally, educators teaching diverse students, and writers targeting broad audiences. Global companies must localize branding and content for each market’s conventions.

Teachers should clarify which variant students should adhere to in assignments and assessments. Writers should tailor manuscripts for publishers and publications in different countries.

Neglecting these discrepancies could undermine marketing campaigns, disadvantage students unfamiliar with the expected variant, or necessitate editing for unsuitable manuscripts.

However, acknowledging these differences enables one to toggle between conventions and averts blunders. An awareness of the key differences between American and British writing is essential for effective communication in our globalized age.

Impact on International Communication

As illustrated, divergent spelling, vocabulary, grammar and style rules between American and British English can lead to confusion, misinterpretation and even offense in cross-cultural written communication. Being mindful of these differences enables clearer correspondence.

Writers targeting international audiences, educators teaching diverse students, and businesses operating globally should all be cognizant of distinctions between American and British English conventions. This awareness helps localize content and avoid blunders that could undermine messaging and engagement across different markets.


In summary, several key differences between American and British writing are important to be aware of. Spelling is one of the most obvious areas where American and British English diverge, with words like “color” vs “colour” reflecting the variations.

Vocabulary also differs, with different terms used in each variant for the same concepts. For example, Brits say “lift” while Americans say “elevator.”

Grammar and punctuation rules also vary between the two forms of English. Americans tend to use simpler grammar with shorter sentences, while British writing features more complex grammar and longer sentences. Stylistically, British English is viewed as more formal and reserved than casual and direct American English. These stylistic differences extend to tone and word choice.

Recognizing these differences is important for clear communication and avoiding misunderstandings, especially for international businesses and writers catering to diverse audiences. When writing for a global audience, it’s best to be aware of divergences in spelling, vocabulary, grammar and style between American and British English.

The key takeaway is that language is dynamic, shaped by cultural and geographical contexts. While American and British English share a common foundation, they have evolved in different directions. For effective communication across regions, it’s valuable to recognize these variations in writing conventions.

With this knowledge, you can make informed choices when writing for different audiences. You may adopt American or British English fully for consistency or strategically use a mix of conventions depending on your readers. Most importantly, be aware that these differences exist, and recognize that adapting your writing is about connecting with your readers, not which variant is “correct.”

When writing or communicating with an international audience, take a moment to consider the conventions being used. Are there spelling, vocabulary, grammar or style differences that could lead to misinterpretation or confusion?

Adjusting your language to align with your readers’ expectations is a simple way to help ideas flow smoothly. With some mindfulness of writing conventions, we can bridge geographical divides and communicate effectively across borders.
