chair

1. Origins, structure, and basic meaning

• Structure: 椅 has 12 strokes and appears in words for chairs.
• Basic usage: 椅子（いす） means a chair; 車椅子（くるまいす） means a wheelchair.

2. Common pitfalls and similar expressions

• The whole-word reading
  • The two characters in 椅子 are read together as いす. This reading is retained in 車椅子.
• Including a means of movement
  • 車椅子でも通れる means that passage is possible in a wheelchair too. でも includes wheelchair use, and 通れる expresses the ability to pass through.
