Refine By

Our readers are primarily accustomed to US English, so use “vacation” over “holiday,” “accommodations” (plural) instead of “accommodation” (singular) and “center,” “color” and “personalize” instead of “centre,” “colour” and “personalise.”

For this reason, commas and periods go inside quotation marks, even if they are not in the original material.

If you’re writing specifically for a UK English-speaking audience, the reverse should be followed. If you have a question about writing in US or UK English, don’t hesitate to reach out to our US or UK copywriters.
