Latin often adds prefixes (originally prepositions) to the beginning of verbs to either emphasize the meaning of the verb or to create a compound verb with a slightly different meaning. Learning these prefixes means that students will not have to learn each separate compound verb for vocab quizzes (ex. convenio, convenire, conveni, conventurus - to come together, convene) because they'll already know the meanings of the prefix (con - cum - with or together) and the base verb (venio, venire, veni, ventus - to come). This means both less work and an easier time with reading Latin! Yay!
