change to the opposite
A change that makes something go or be the opposite of what it was before.
用法模式：
a reversal of [something]
常见错误：
Learners sometimes use *reversion* instead of *reversal* for everyday changes (e.g., *a reversion of policy*). In general English, *reversal* is the natural choice for changes to the opposite, especially with decisions, policies, and trends.
近义词
U-turn (Often used in politics and everyday speech for a sudden, clear change to the opposite position; more informal.)
|
about-face (Stresses a sharp, decisive change, especially in opinion or policy; can sound slightly dramatic.)
反义词
continuation (Emphasizes that something keeps going in the same direction or way instead of changing to the opposite.)

defeat or serious setback
A defeat or big problem that stops progress or success for a person, group, or plan.
用法模式：
a [major/serious] reversal for [someone/something]
常见错误：
Learners may think *reversal* in this sense always means a complete change to the opposite. Here it often means a defeat or loss that harms progress, not necessarily a full change to the opposite situation.
近义词
setback (Very close in meaning; the most common everyday alternative for a negative event that slows or harms progress.)
反义词
breakthrough (Describes a sudden, important success that pushes progress forward, opposite to a reversal that pushes it back.)

近义词

反义词
