漸次

1. Origins, structure, and basic meaning

• Structure: 漸次 is read as ぜんじ and is an adverb for a change or process proceeding gradually or in stages rather than all at once.
• Basic usage: A replacement plan appears in 漸次交換される, while progressive change appears in 漸次変化する.

2. Common pitfalls and similar expressions

• Difference from 徐々に
  • Both express gradual change, but 漸次 is more literary and common in descriptions of plans or processes, while 徐々に is also frequent in everyday speech.
• Progress by stages
  • The focus is not merely slow speed but change advancing progressively through an order or area.
