“candidate”是名词，意思是“候选人、应试者、求职者、人选”，具体意思要取决于上下文。英英释义：a person who applies for a job or is nominated for election. 比如竞选总统的人就叫 presidential candiate；上完了博士阶段的课程，正在写博士论文的学生一般被叫做 doctoral candidate 或 PhD candidate；找工作的也可以叫 candidate。
例句:
① 比如前不久美国前副总统 Joe Biden 决定竞选下一届美国总统，我们可以说：
Joe Biden decided to run for president in 2020.
用 candidate 来改写：
Joe Biden recently decided to join others as a presidential candiate.
② 好几个博士候选人都放弃了博士学位，跑到硅谷去创业：
Quite a few PhD candidates gave up their doctoral degree and moved to Silicon Valley to start start-ups.
③ 目前只有五个人对这个销售职位感兴趣，我们就可以说：
So far only five candidates have shown interest in this sales position.
