Prefer American over British spelling (EK00001)

American English spelling keeps your documentation consistent with the tools and libraries readers use. Learn why to prefer it over British spelling.

American English spelling keeps a single convention running through your documentation, so words like color and organize don’t compete with colour and organise. EkLine flags British spellings (rule EK00001) and suggests the American equivalent so you can standardize your text.

Why use American spelling in documentation?

Section titled “Why use American spelling in documentation?”

Mixed spelling conventions make documentation look unedited and distract technical readers. Most software and API documentation follows American English, and matching that expectation keeps your content consistent with the tools, error messages, and libraries your readers already use. Consistent spelling also improves search: readers who search for initialize shouldn’t miss a page that only says initialise.

EK00001 matches British spellings anywhere in your text, regardless of case, and suggests the American form.

Accept the suggested American spelling, or apply it yourself. When a British spelling is intentional — for example, in a product name, a quotation, or a proper noun — keep it and silence the rule for that content.

Is American or British spelling better for documentation?

Section titled “Is American or British spelling better for documentation?”

Neither is more correct, but most software and API documentation follows American English. Matching that convention keeps your content consistent with the tools, error messages, and libraries your readers already use.

Can you keep a British spelling on purpose?

Section titled “Can you keep a British spelling on purpose?”

Yes. When a British spelling belongs to a brand name, a quotation, or a proper noun, keep it and ignore the rule for that line.
