When writing for an international audience, especially in academic or professional contexts, it’s essential to know which variety of English you’re expected to use. You may be asked to write in British English, American English, Canadian English, or Australian English, but UK vs. US English is the most common distinction requested by our clients.
Understanding the differences between these two dialects helps ensure consistency and professionalism in your writing.
Although spelling and grammar tools have improved, they don’t always catch every dialect-specific error. Many essays and manuscripts still contain avoidable inconsistencies. Knowing the key differences between UK and US English will help you avoid mistakes and improve the clarity and credibility of your writing.
The table below highlights some of the most frequent spelling errors made by ESL writers.
Dilemma | US English | UK English |
---|---|---|
z or s? | organize, generalize, analyze | organise, generalise, analyse |
-or or -our? | color, flavor, behavior | colour, flavour, behaviour |
l or ll? | labeled, traveled, modeling | labelled, travelled, modelling |
s or c? | practice (noun & verb) | practice (noun) / practise (verb) |
-er or -re? | center | centre |
In addition to spelling, UK and US English differ in vocabulary. The same object or concept can have entirely different names depending on the dialect. It’s important to use region-appropriate terms—especially in formal writing.
Use a trusted dictionary when in doubt:
