Most of the usage of "matter-of-factly" that I've seen is to describe a manner of speaking - "He said, matter of factly,...", etc.

A friend brought up the following usage, which seems wrong, but I can't pinpoint exactly what is wrong. "Matter of factly, I don't know. I know from my dad's experience."

What's the view on this?

Couple of points:

  • The adjective form "As a matter of fact, I don't know. ..." seems correct.
  • Similar usage of literally works: "I literally don't know." or "Literally, I don't know"
  • I have seen usage of ''matter of factly '' in a lot of Danielle Steel's novels.

The issue with the second usage is that "matter-of-factly" means "in a matter-of-fact style"; it is not synonymous with "as a matter of fact". "As a matter of fact" is by itself already an adverbial phrase (meaning "actually"); tacking an additional -ly on the end to re-adverbialize it can't be right.

I'd be more inclined to express your friends' apparent intended meaning as "I don't know personally" or "I don't know directly".

  • Thanks Hellion, "As a matter of fact" meaning "actually" makes sense, and comparing it with the adverb form is where I was going wrong.

I've never heard it, and BYU's COCA has but one example of it (and q.v., as I'm not sure even it's in this sense). So, short answer, maybe it's an up-and-coming usage or maybe it's a one-off your friend heard, but in any event don't put it in your written work — yet.
