Verisimilitude:
The quality of realism in a work that persuades the reader that he/she is getting a vision of life as it is.


Example:
"While i was attending to those in front, and on either side, the one behind ran up with the hand-spike, and struck me a heavy blow upon the head. I fell, and with this they all ran upon me, and fell to beating me with their fists... with his heavy boot, a powerful kick in the left eye."
-Frederick Douglass: An American Slave

Explanation:
Douglass deeply describes himself getting beat up. This imagery allows the reader to actually image what Douglass went through. Douglass does this on purpose, so the reader gets a vision of reality for the slaves, and the reader will want to change things, and make sure the slaves are free or treated better.
