Example of actions speaking louder than words: let’s say you ask your friend not to do something and they say they won’t do it again but they continue to do it then you bring it up again and they say they won’t but continue to do it. Their actions are speaking louder than their words.
The topic—"Literary devices in American poetry"—would be a weak topic because such a topic is extremely vague and not specific enough.
American poetry uses many, MANY literary devices—and many of which are not unique to American poetry alone. Also, "American poetry" in general is too broad of topic.
General Rules:Don't Use "a," "an," or "the" with a plural count noun when you mean "some of many things," "any," "in general.
Ex:"<span>Movies are entertaining (some movies; movies in general).
<span>
Ex:He likes women (in general).</span></span>
