• flush

  Often used as 'a flush of' plus an emotion noun, describing a sudden rush of feeling; more literary, sometimes paired with a reddening of the face.

Boot and flush both mean a strong feeling of excitement. Boot appears only in 'get a boot out of it', sounding informal and old-fashioned. Flush is often 'a flush of excitement', more literary, sometimes with a red face. Other meanings are not compared here.

这两个词在表示“兴奋或愉悦带来的强烈快感”时意思相近，但语域和搭配不同：boot 几乎只出现在固定短语 get a boot out of 中，语气随意、略显过时；flush 常与 of 连用（a flush of excitement），风格更偏书面，也常伴随脸部泛红的生理反应。这里不比较 boot 的“靴子”“（英式）汽车后备箱”“（计算机）启动”等义项，也不比较 flush 的“脸红”“冲水”“扑克同花”“大量、充裕”等义项。
