粒度

1. Origins, structure, and basic meaning

• Structure: 粒度 is read as りゅうど and is a technical noun for particle size or granularity, treated as something to compare or adjust.
• Basic usage: It is used when measuring material particles or tuning a powder to achieve a desired texture.

2. Common pitfalls and similar expressions

• Measured property
  • In 粒度を比べる and 粒度を調整する, the word denotes a material property rather than one individual grain.
• Contextual wording
  • Particle size fits the sand comparison, while granularity fits adjustment of a powder’s texture.
