よくある間違い：
Learners sometimes confuse 'sediment' with 'segment' because they look similar. 'Sediment' is material at the bottom of a liquid, while 'segment' means a part or section of something. Another mistake is using it only in scientific contexts; it is also common with drinks like wine or coffee.
意味
solid material at a liquid's bottom

よくある間違い：
Learners may think 'sediment' in this sense only refers to sand. In geology and environmental science, it also includes silt, clay, gravel, and organic material. Another confusion is using it as always uncountable; in technical writing, you may see 'different sediments' to mean different types or samples.
意味
natural deposits of loose material
コロケーション
river sediment
|marine sediment
|sediment layers
|sediment deposition
|sediment build-up
|sediment accumulation
類義語
deposits (General term for material laid down over time; not limited to particles carried by water or wind and can include chemical or mineral deposits.)
対義語
bedrock (Refers to the solid rock beneath soil and sediment, contrasting with loose surface materials.)

定義
Loose pieces of rock, sand, or soil that are moved and then left in a new place by rivers, the sea, wind, or ice.
Loose material such as sand, silt, clay, or gravel that has been transported and deposited by water, wind, ice, or gravity, often forming layers on the Earth's surface.

よくある間違い：
Learners often use only the noun 'sediment' and do not realize it can be a verb in scientific writing. Another mistake is using 'sediment' as a verb in everyday speech; outside technical or lab contexts, people usually say 'settle' instead.
意味
to settle out of a liquid
コロケーション
allow to sediment
|cells sediment
|sediment rapidly
|sediment slowly
|sediment out of solution
|particles sediment
類義語
settle (More general and common; can describe many things coming to rest, not only particles in a liquid. 'Sediment' is more technical and specific.)
対義語
suspend (In scientific contexts, means to keep particles mixed and floating in a liquid, preventing them from settling as sediment.)
テーマ

定義
To move down through a liquid and sit at the bottom as solid material, or to make something do this.
