American vs British English in Scientific Manuscripts

One common question for researchers preparing manuscripts for international journals is whether to use American or British English. Both forms are acceptable in scientific writing, but consistency is essential.

Many journals based in the United States prefer American English, while UK- and Europe-based journals often favour British English. This affects spelling (color vs colour, analyze vs analyse), punctuation conventions, and some terminology.

Problems arise when a manuscript mixes the two systems. Inconsistent spelling and usage can distract reviewers and may be flagged during editorial checks, even when the science itself is sound.

Professional scientific proofreading ensures that the manuscript follows a single, appropriate variant of English throughout. Proofreaders also align language choices with the expectations of the target journal, reducing avoidable revisions at the submission stage.

Choosing the correct variant of English and applying it consistently helps present research clearly, professionally, and in line with international publishing standards.
