1
gradually wear away material
To slowly wear away and remove rock, soil, or other material, usually by water, wind, or ice.
用法パターン：
to erode [material/place]
よくある間違い：
Learners sometimes confuse "erode" with "corrode". "Erode" is usually about physical wearing away by water, wind, or ice (rivers erode rocks), while "corrode" is about chemical damage, especially by rust or acid (acid corrodes metal). Also, "erode" can be both transitive and intransitive: "The river erodes the bank" and "The bank is eroding."
類義語
wear away (More general and informal; can refer to physical or abstract things, not just natural forces.)
|
weather (Often used in geology for slow change by weather; can also mean simply "to survive" in other contexts.)
対義語
build up (Describes the opposite process of material being added or accumulated instead of removed.)
|
deposit (In geology, refers to material being laid down, the reverse of being carried away.)

gradually weaken something abstract
To slowly make something like trust, confidence, power, or rights weaker or less.
用法パターン：
to erode [abstract quality]
よくある間違い：
Learners sometimes use "destroy" instead of "erode" in these contexts. "Destroy" suggests something is gone suddenly or completely, while "erode" suggests a slow, step-by-step weakening. Also, do not use people directly as objects: say "erode his confidence", not "erode him".
類義語
undermine (Very close in meaning; often used more broadly for secretly or slowly making something weaker.)
|
weaken (More general and common; does not always suggest a slow or gradual process.)
対義語
strengthen (General opposite, meaning to make an abstract thing stronger instead of weaker.)
|
reinforce (Focuses on adding support so that something like trust or belief becomes harder to erode.)

gradually reduce financial value
To slowly make money, profits, or value less, often because prices go up or costs increase.
用法パターン：
to erode [money/value/profits]

類義語
diminish (General word for becoming smaller or less; not limited to financial contexts.)
|
eat into (Informal phrasal verb that emphasizes costs or problems taking away money or time.)
