根元

1. Origins, structure, and basic meaning

• Structure: 根元 is read ねもと and refers to the base of a tree or plant where its roots connect.
• Basic usage: It is used for leaves around a tree's base or the position at which grass is cut.

2. Common pitfalls and similar expressions

• Root and base
  • 根 names the root itself; 根元 names the base where the roots connect. It does not necessarily refer to the entire underground root system.
• Location and cutting point
  • 根元に落ち葉が積もる identifies where fallen leaves accumulate.
  • 根元から切る means cutting at the base, which is different from pulling the plant out by its roots.
