Answer:
The positive and lively connotation.
Explanation:
The word action comes to mind when I think of a movie scene that starts when somebody shouts: 'Action!'
In writing it is important for its lively contribution to any kind of subject that could be pretty boring if it were too theoretical: If I want to explain an abstract noun, I prefer saying: You can see and touch the happy boy, but you cannot touch his happiness. These actions (to see & to touch) help a lot.
In speaking it is quite different because it depends on how you explain something. The way you move your head, the look you have, the tone of your voice. Nevertheless, the eloquence of the speech is important too, and I dare say that eloquence is also a form of action, because your brain is very active in order to construct well-thought and logical phrases.
