The American Civil War greatly caused a dramatic shift in style, form,
and thematic discourse in American literature because it affected the
people in a way that they question its morality and reality. The works
after the Civil War were mainly focused on how they experienced the war
and its effects. It also sparked some antiwar works and some focused
more on patriotism.
Are there options? If not, I believe you meant to write glib? If I am not mistaken a good definition would be fluent, smooth, easy and unconstrained. Hope this helps!
