Logastellus: A person whose love of words is greater than their knowledge of words.
Fortunately for Loki, Modi seems to have inherited not only his mischievous nature, but also his ability to sit still in the cradle of Loki's lap and read a book. Or, at the very least, pretend to read, which is far more than Loki can say about Thor.
Before Modi is ten months old, he has already begun to trace the curves of the letters and runes and inscriptions on the onionskin pages in Loki's lap with the tip of his finger, and Loki smiles indulgently, presses kisses into Modi's blonde curls, and allows his son extra time on each page, even if Modi's fingers are sticky with jam and he smears purple across the paragraphs.
"Here," Loki says one day, opening a thick book on his lap and patting his knees for Modi to climb in. "There's a character in this story that likes potatoes very much." At the mention of the spud, Modi's face brightens and he climbs obligingly into Loki's lap, snuggling back into Loki's stomach as Loki begins to read The Lord of the Rings to him, in a soft, melodious tone.
Thor, grudgingly curious about this Frodo fellow (it sounded suspiciously like the name of a great warrior in another Midgardian series Loki was currently obsessed with - Thor would later learn that Loki had been talking about Drogo, not Frodo), stands hidden behind the nursery door and listens in.
Loki, looking over, sees Thor's hulking silhouette in the doorway, smiles, and reads just a bit louder for his benefit.
