'Trivial spells' were categorized as spells that weren't official. Even apprentice Mages would be able to execute these fundamental spells. They were extremely easy to learn in normal situations, and the construction of the spells was so simple that even young children could understand. But the corresponding effects were extremely limited, and the functionality was very direct. In fact, many of the trivial spells didn't possess any practical usage for combat or work. They could only serve as support spells for official spells or 'preschool education'.
