持つ

1. Origins, structure, and basic meaning

• Structure: 持つ (もつ) is a godan transitive verb for physically holding and carrying an object or possessing an opinion or thing.
• Basic usage: 箱を二人で持って運ぶ physically supports and carries a heavy box, while 自分の意見を持っている describes possessing a definite personal view.

2. Common pitfalls and similar expressions

• Physical carrying and possession of an opinion
  • 箱を持つ means holding an object, while 意見を持つ means possessing a view. These inputs do not support a separate sense of maintaining a state, so the verb is not extended to that scope here.
