用法筆記
The particle 'up' (fatten up) is common in everyday speech and adds a sense of 'fully' or 'completely' — e.g., fatten up a sick child, fatten up a thin calf. Figuratively, fatten can refer to increasing the size or amount of something non-physical, such as a bank account, budget, or document. In these uses the transitivity is always active (transitive); the intransitive pattern (fatten on + food) is restricted to animal subjects.
