straight（径直）加away（走开）：直直地马上就走，毫不拖延，所以是“立刻”。
语域：mixed 常见场景：日常对话、一般书面叙述 该词表示“立刻、马上”，多用于日常对话或一般书面叙述；在正式公文或学术写作中，选用 immediately 会更稳妥。
真正与 straightaway 词尾 /weɪ/ 押韵的词有：away /əˈweɪ/、freeway /ˈfriːweɪ/、highway /ˈhaɪweɪ/、day /deɪ/（day 的元音和尾音与 /weɪ/ 相同，只是开头辅音不同）。注意：straight 和 strait 都读 /streɪt/，只对应 straightaway 的开头音节，不与整个词押韵；此外 straightaway 是重音在前的复合词 /ˈstreɪtəˌweɪ/，不要按 straight + away 两个词连读。
