係員

1. Origins, structure, and basic meaning

• Structure: 係員(かかりいん) refers to a staff member assigned to provide guidance or handle a particular task.
• Basic usage: It identifies the person responsible when seeking help at a ticket gate or following instructions at a facility.

2. Common pitfalls and similar expressions

• Affiliation and assigned work
  • 社員 identifies someone as a company employee, whereas 係員 focuses on the duty assigned at that location.

  • かかり joins with いん to form かかりいん. After り, the い takes a separate beat.
