Step 1: Trace the Latin root of Voracity.
"Voracity" comes from the Latin "vorare" meaning "to devour or swallow"; the same root gives us "voracious" (having a huge appetite); the suffix "-ity" forms an abstract noun denoting the quality of something.
Step 2: Watch for the common confusion.
Students often mix up "Voracity" with "Veracity" (from Latin "verax" = truthful) which means truthfulness or accuracy; key distinction: Veracity = truth; Voracity = greed.
Step 3: Identify the correct meaning.
Voracity means extreme greediness or eagerness, especially in consuming or gaining things; among the options "greed" is the closest match; truthfulness, kindness, and calmness are completely unrelated.
