A stamp may show any kind of information, such as a date, a few words or a symbol. A seal is more official, and is likely to appear on legal documents. Both words can be used figuratively to show that sth has been approved. * stamp的含义比seal更宽泛，可以显示任何信息，如日期、语句或符号等；seal更为正式，而且多出现在法律文件上。两个词都可用于比喻义，表示某事已获批准◆ (figurative) The project has the government's seal / stamp of approval.工程已获政府批准。■colours (BrE) (NAmEcolors) [plural] (especially BrE) a flag, badge, etc. that represents a team, country, ship, etc（代表团队、国家、轮船等的）旗帜，徽章◆Most buildings had a flagpole with the national colours flying.大多数建筑物都有旗杆，上面悬挂着国旗。■insignia / /ɪnˈsɪgniə/ / [uncountable + singular or plural verb] the symbol, badge or sign that shows sb's rank or that they are a member of a group or organization（表明级别或成员身份的）标记，徽章，证章◆His uniform bore the insignia of a captain.他的制服上有上尉徽章。■crest [countable] a design used as the symbol of a particular family or organization, especially one that has a long history（尤指历史悠久的家族或机构的）饰章，纹章◆The family crest consists of a crown and an eight-pointed star.这个家族的饰章由皇冠和八角星组成。NOTE辨析 Arms, emblem or crest?A coat of arms is found on a shield, and often displays particular designs such as standing lions or large feathers. A crest traditionally appeared above a coat of arms, but can now be used alone, and suggests that the owner has a high reputation and great respect. Emblem is a more general word: a coat of arms or a crest can be regarded as emblems, but emblem is usually used to describe sth smaller that represents an organization. * coat of arms指盾牌上的徽章，常为某种图案，如站立的雄狮或大羽毛。crest传统上会出现在盾徽的上方，但现在也可独立使用，暗示其主人声望很高且备受尊敬。emblem含义更广，coat of arms或crest可被看作是emblem，但emblem通常指代表某机构的小型徽章。
