other

1. Origins, structure, and basic meaning

• Structure: 他 means other or additional things and is read ほか or た in compounds.
• Basic usage: 他人, read たにん, means another person; その他, read そのた, means other things or the rest.

2. Common pitfalls and similar expressions

• Another person and a stranger
  • 他人の手紙 means someone else's letter, rather than one's own.
  • 他人 does not always mean someone never met before, so stranger is not its only English equivalent.
• Grouping what remains
  • In 机や椅子、その他の備品, その他 groups equipment other than the desks and chairs already mentioned.
  • その他の条件 means additional conditions; the range depends on what has already been listed.
