除了 + Noun + 以外, 都/也/还 + Clause
以外 means "besides," "except for," or "in addition to," placed after a noun or phrase preceded by 除了. Depending on whether the main clause uses 都 or 也/还, it can mean "except for" (exclusion) or "in addition to" (inclusion). This flexibility makes 除了…以外 one of the most versatile structures in Chinese.
