除外

1. Origins, structure, and basic meaning

• Structure: 除外 is read as じょがい and is a noun and する verb for removing a particular item from a defined set, calculation, or scope.
• Basic usage: The basic pattern is AをBから除外する; foregrounding the excluded item produces the passive Aが除外される.

2. Common pitfalls and similar expressions

• Difference from 削除
  • 削除 erases data or text itself; 除外 leaves the item possible but does not include it in a particular scope.
• Identify both elements
  • Check not only what is excluded but also the tally, tour group, or other source set named before から.
