We are naturally concerned very much by/about our appearance.

In this sentence, which preposition should be used, by or about? Are there any other prepositions used after the word "concerned"? Thanks in advance.

  • I would pick "about", since "by" seems to imply wilful action. Feb 23 '16 at 8:41
  • Thank you, CopperKettle. I found the sentence in a test question.

  • @CopperK - I would choose "about" also, but for a different reason. We simply tend to use about more than by with concerned.

  • BTW I think you should say: very much concerned not concerned very much

"About" is the correct choice because "by" implies action on the part of "appearance". E.G.

I was pulled over by a trooper

He was hit by a bus

That book is by John Smith

Alternately, you might use "concerned with", but really "concerned about" is most common.


I could depend on "how" (by what method) you saw yourselves -- perhaps in a mirror, on a TV broadcast, reflected in a window, or in your minds' eyes?

In other words, if it was a physical sight, a reflection for example, then "by" is appropriate. This is like saying, "when I saw my reflection, I was shocked by it."

If you are thinking about how you look, then "about" is more appropriate, as the previous answer says. "I spent a lot of time getting dressed because I was concerned about my appearance."
