📜 The Origin of “More So”

The phrase “more so” comes from the combination of the adjective “more” + adverb “so.”
It’s been used in English since the 16th century to mean to a greater degree or to a larger extent.

The one-word version “moreso” appeared later as a modern blend, mostly due to fast typing and informal online speech. However, it never gained recognition in dictionaries like Oxford or Merriam-Webster.

In short, “more so” is the historical, grammatical, and correct version.
