Angary is a legal term which refers to the right of a nation to seize or detain foreign vessels or goods temporarily in times of war or unrest. It is not a term that is frequently used in everyday language, and therefore not many synonyms exist. However, there are some phrases that could be used as alternatives in certain contexts. For example, the concept of "requisition" or "impressment" might be used interchangeably with angary in some circumstances, but these terms do not necessarily have the same legal significance or authority. Other possible synonyms could include "confiscation," "seizure," or "appropriation," although these words may not capture the nuances or implications of angary precisely.
