Most text in the game is in the message dialog files (see that section). But there's a handful of places where individual words and short phrases are stored in their own structured tables, each with its own quirks.
The magic glyph keyboard
377 little icons make up the player's spell-casting vocabulary. Each one is a word like "morning," "river," "Vivian," or "happy."
Food and recipes
192 named food slots. Most are simple, but 10 are "multi-name" slots holding arrays of variant names keyed by ingredient pairs.
The ARM9 menu pool
The short action verbs that appear on the inventory menu β "Hold," "Place," "Bury," "Equip." They're embedded directly in the game's main binary with strict byte budgets.
