When is the universal theme of story often revealed

The universal theme of a story is often revealed at the resolution of the story, when the reader can see how the story ends. In literature the terms of "theme" and "universal theme" are commonly used

voracity is the noun corresponding to the adjective voracious, which means (1) eager to consume a great amount of food, or (2) marked by an insatiable appetite. veracity is far more common than the rare voracity, so the latter is sometimes used in place of the former.
