outboard(形容词/名词)常指(安装在船外的)舷外的;舷外发动机。最常见用法是 outboard motor/engine,即小船上可拆装的舷外机。(也可引申为“靠外侧的”,如 outboard seat,但不如船用义常见。)
/ˈaʊtbɔːrd/
We bought an outboard motor for the fishing boat.
我们给渔船买了一台舷外发动机。
With a reliable outboard engine, the small skiff could handle rougher water and longer trips.
有了可靠的舷外发动机,这条小艇就能应对更颠簸的水面和更长的航程。
由 out-(在外、向外)+ board(船舷、船侧;也有“上船/木板”等相关义)组合而成,字面意思是“在船舷外侧的”。随着小型船用动力普及,逐渐固定指代安装在船外的发动机。
