吸水

1. Origins, structure, and basic meaning

• Structure: The written form is 吸水, read きゅうすい. Elements for drawing in and for water combine to denote the action or capacity of absorbing water.
• Basic usage: 吸水が速い describes a cloth’s absorbent performance, while 吸水の速さ turns absorption rate into a quantity for comparison.

2. Common pitfalls and similar expressions

• Material performance
  • How quickly the cloth takes in water is linked to its usefulness. Example: この布は吸水が速く、台所で使いやすい。 — This cloth absorbs water quickly and is convenient in the kitchen.
• A comparable rate
  • The experimental context compares how quickly soils absorb the same amount of water. Example: 乾いた土に同じ量の水を注ぎ、吸水の速さを比べた。 — We poured the same amount of water onto dry soil and compared absorption rates.
