順次

1. Origins, structure, and basic meaning

• Structure: 順次 (じゅんじ) is an adverb for proceeding one after another in an established or readiness-based order.
• Basic usage: 部屋から順次利用を始める opens rooms one by one as they become ready, while 商品は順次並べられる has completed goods placed in stores successively.

2. Common pitfalls and similar expressions

• Readiness order and successive handling
  • 順次利用する and 順次並べる show that processing is successive rather than simultaneous. They do not necessarily mean ascending numerical order.
