English Proofreading for Different Dialects: US vs UK English

English proofreading for different dialects

1. Spelling differences

Let’s start with the most visible distinction—spelling. Here are the most common patterns:

–our vs. –or

Rule of thumb: US English prefers simpler spellings with –or endings.

–re vs. –er

Exception: “meter” is used for measuring devices in all variants.

–ogue vs. –og

“Dialog” is often used in tech/UI, but “dialogue” is still common in prose.

–ise vs. –ize

Note: UK English often accepts both, but US uses –ize almost exclusively. Interestingly, –ize spellings actually originated in the UK. Style guides like Oxford still prefer this version. When in doubt, prioritize consistency.

–yse vs. –yze

2. Grammar and usage differences

Past tense forms

Some verbs have different past tense forms depending on the dialect:

“Gotten” in US English is used to indicate change or acquisition, e.g., She’s gotten better.

Collective nouns

• UK: Can use singular or plural depending on context
  The team are winning tonight.
• US & AUS: Typically singular
  The team is winning tonight.

When the group is acting as individuals, plural is correct in all dialects: The team are arguing among themselves.

Present perfect vs. simple past

UK prefers present perfect for ongoing relevance. US leans into the simple past.

3. Prepositions

Even prepositions vary:

4. Articles with place names

Some place names include “the”, while others don’t:

Tip: If unsure, check the common usage or consult a reliable dictionary or style guide.

5. Double consonants in word endings

UK/AUS often double final consonants with suffixes, while US English usually does not:

This also applies to: channelled vs. channeled, modelling vs. modeling.

6. Noun–verb differences

7. Word preferences

Some everyday words differ by region:

Tip: Regardless of region, program is the standard in computing contexts. Reserve programme for non-technical uses, like TV shows or event schedules, especially in UK English.

8. –ough: Spelling and pronunciation challenges

Words with the combination –ough can be tricky to spell due to their irregular pronunciation. For example:

• Cough (rhymes with off)
• Rough (rhymes with buff)
• Through (rhymes with shoe)
• Though (rhymes with show)

9. When to use en dash and em dash:

Let’s talk about the rebel of the punctuation world. Just because AI keeps throwing em dashes everywhere doesn’t mean we should eliminate them from our writing. The key is knowing when and how to use them—especially across dialects.

En Dash (–)

Use it when you’re showing:

• Number ranges: Pages 45–68 are optional.
• Scores and results: Turkey won 3–1 against Italy.
• Links or conflicts between words: Human–machine collaboration is evolving fast.
• Compound adjectives with proper nouns or multi-word terms: A Berlin–based startup
• In UK/AUS English: She finally replied – two days later. => Spaced en dashes are often used parenthetically or in place of colons.

Em Dash (—)

This one adds flair—but it’s often misunderstood.

• To insert extra info (instead of parentheses): He was late—as usual—but no one complained.
• To add punch at the end (like a colon): She had one rule—no excuses.
• To break off dialogue: “Wait, don’t touch that—”
• Standard in US English: Let’s get started—no more delays. => no spaces.

In the UK and Australia, spaced en dashes are still more common in this role. But ultimately, it depends on the style guide your client follows.

Although these words are pronounced similarly, their spelling can vary, leading to common errors. Double-check words like these during proofreading, particularly for ESL writers who might struggle with English’s inconsistent spelling rules.

If your content switches between US and UK rules, editors notice. Clients too. I fix that. See my proofreading and editing services.

Common English usage confusions

Humor vs Humour – Which spelling should you use?
“Humor” is standard in US English, while “humour” is used in UK and Australian English. Both are correct, but mixing them in the same text signals poor editorial control.

e.g. vs ex – What’s the difference?
“e.g.” means “for example.” “Ex” doesn’t replace it and is incorrect in this context.

Your old vs you’re old – Why spellcheck misses this
“Your” and “you’re” are both valid words, which is why spellcheck tools often fail to catch this error. Proofreading focuses on meaning, not just spelling.

Is euchre capitalized?
“Euchre” is capitalized because it’s a proper noun referring to a specific card game. Lowercase usage is considered incorrect in edited writing.

American vs British spelling checkers – are they enough?
Grammar tools can detect spelling differences, but they often miss context-based rules and consistency issues.

5 tips on English proofreading for different dialects

Always check your client’s language preferences before proofreading.

• Set your spellcheck tool correctly: Always match your proofing language (US, UK, or AUS) in your writing software before starting.
• Watch for dialect markers: Words like favour, realise, or licence usually indicate UK English. Color, organize, or practice as both noun and verb suggest US English.
• Use trusted resources: If you’re unsure, check spelling and usage in regional dictionaries like Merriam-Webster (US) or Oxford (UK). Style guides help too.
• Be mindful of grammar patterns: Collective nouns, verb tenses, and even prepositions shift by dialect. For example: Have you eaten yet? (UK) vs. Did you eat yet? (US).
• Stay consistent: Mixing dialects in a single document weaken editorial trust. Pick one variant and stick with it from title to CTA.

Proofreading is the last phase in content creation process

Proofreading is the final checkpoint in your content creation journey. Earlier editing stages focus on structure and clarity, but proofreading catches those last-minute errors that could you show super amateur. 

The traditional editing workflow typically involves:

• Substantive Editing: Restructuring the manuscript for flow, clarity, and content development alongside the author.
• Copy Editing (Mechanical Editing): Addressing grammar, spelling, punctuation, word choice, and aligning content with specified style guides.
• Proofreading: Detecting leftover errors prior to publication, such as grammar, spelling, formatting, capitalization, and typesetting issues.

Today, freelance proofreaders often merge proofreading with elements of copy editing, guided by the specific style preferences of each client. But proofreaders’ main goal is consistent accuracy throughout your content.

Lastly, I also want to clarify an aspect that often causes confusion: the sequence of stages in content creation. For instance, fact-check content is a distinct step that comes before proofreading but many people mix the two. Plus, those two are different expertise. Proofreader doesn’t responsibility from claim’s accuracy. And the reverse is also true; fact-checkers don’t polish grammar, punctuation, or formatting.

The full content creation process generally follows this order: Briefing → Researching → Outlining → Writing → Editing → Fact-Checking → Proofreading.

This meticulous review ensures your content is error-free, polished, and publication-ready.
