Moreso or more so is a phrase people often Google after second-guessing a sentence they’ve just written. It looks like one of those cases where English lets you choose either option—but that’s not quite true. The confusion usually pops up in essays, emails, captions, or even professional writing, where clarity really matters.
Let’s break it down clearly and confidently so you never hesitate again.
Quick Answer: Moreso or More So?
Moreso or more so has a simple rule:
-
“More so” (two words) is the standard and preferred form.
-
“Moreso” (one word) exists but is considered nonstandard or informal in most modern writing.
If you want to be safe, polished, and correct, use “more so.”
What Does “More So” Mean?
At its core, more so means:
-
to a greater degree
-
to an even larger extent
-
especially or particularly
Example:
I enjoy traveling, more so when it’s unplanned.
Here, more so emphasizes degree, not comparison.
Where Did This Confusion Come From?
Historically, “more so” has always been the grammatically correct construction in English. It evolved naturally from comparative phrases like more than or even more.
“Moreso” appeared later as an informal shortcut—likely from spoken language where the words blend together. While some dictionaries list it as a variant, style guides and editors overwhelmingly prefer more so.
