expression, godan verb (-ku)
lift a ban; remove a prohibition
Used when an official or formal restriction is ended. Often appears in news or legal contexts.
政府は輸入の禁を解くことを決定した。
The government decided to lift the ban on imports.
Similar meaning but uses 禁止 (prohibition) instead of 禁, which is slightly more formal and often found in compound nouns.
Compound of 禁 (ban, prohibition) + を (object marker) + 解く (to untie, release, solve). The literal image is 'untying a prohibition'.
