電線

1. Origins, structure, and basic meaning

• Structure: 電線 is read as でんせん; 電 (electricity) and 線 (line) combine for an electrical wire or overhead power line.
• Basic usage: Use 電線に小鳥が並ぶ for location on a line and 古い電線を交換する for the item being replaced.

2. Common pitfalls and similar expressions

• Power line and individual wire
  • The roadside line supporting birds is an overhead power line, while the replacement context does not identify the wire’s location; “electrical wire” or “power line” must be selected from fuller context.
• Location and work object
  • に marks where the birds sit, and を marks the wire directly replaced with a new one.
