I'm looking for the specific difference between the words "act" (one thing you do; eg: "an act of violence") and "action" (something someone does; eg: "actions speak louder than words").
Can anyone help me?
We have a difficult time discussing the difference between two words without a specific context to consider. That means, we need sentence in which you might use these words to use as an example to begin the discussion.
However, there are several previous threads on the difference, and they already provide a context. I think that the first may answer your question, but you will want to look at the others as well. (I found them by entering act action in the Look-up box at the top of the page.
