10+ Other Ways to Say “Not Only” (Formal, Informal & Professional Alternatives)

When we want to add extra information, English speakers often reach for “not only.” But using the same phrase again and again can make writing sound repetitive. Learning fresh alternatives helps your writing feel smooth, smart, and natural — and it shows readers (and search engines) that your content is thoughtfully written, not formulaic.

Using varied expressions helps in business writing, emails, essays, and everyday talk. It shows confidence and strong language skills — and it’s exactly the kind of natural, helpful writing that ranks well and reads well.
