Definition
Moth-eaten literally describes something with holes caused by moths 🐛, but metaphorically, it means something old, worn, and dilapidated, often to the point of being useless or unappealing. Think of an old sweater with holes all over it. It can also refer to ideas or systems that are outdated and no longer effective. Imagine a building that's falling apart from neglect. It conveys a sense of decay and deterioration.
