forced control of speech or dissent
The act of a government or group using power to stop people from speaking, sharing news, or protesting.
用法パターン：
the suppression of [information/opposition/protests]
よくある間違い：
Learners often confuse "suppression" with "oppression." "Suppression" is about actively stopping or pushing something down (such as protests or news), while "oppression" is a broader, ongoing unfair treatment of people. Also, do not say *"suppression protests"*; use the pattern *"suppression of protests"*.

The act of controlling or reducing a physical thing like fire, sound, or plant growth.
