"Set up" is a phrasal verb that means to arrange, establish, or prepare something, such as "They set up the new computer in the office." On the other hand, "setup" is a noun referring to the way something is arranged or the process of setting something up, like "The office setup was efficient and organized." A simple trick to remember the difference is that if you can replace "set up" with "install" or "arrange," use the two-word verb; if you're referring to the result or structure, use the one-word noun.

「set up」或名詞形式「setup」在英文裡很萬用，最常見的動詞用法是「安排、建立、組裝」等，例如："We need to set up the projector before the meeting." 表示開會前要把投影機架好；也可以指創立公司或組織，像 "She set up her own company last year."；有時候還帶有「陷害、設局」的意思，例如 "He was set up by his enemies."。名詞「setup」則指「佈置、配置、整個架構」，如 "The setup of the experiment was complicated."，說的是實驗的整體裝置與流程。記得動詞時要分開寫成 set up，名詞或形容詞時則多半連寫成 setup。

Onboarding is the process of helping new employees adjust and get started in a company. It includes things like introductions, training, and setup. For example: "Our onboarding program includes a welcome tour and system training." or "Good onboarding helps new hires feel confident from day one."

談到職場新手時，你常會聽到「onboarding」這個字。簡單來說，onboarding 就是公司協助新人熟悉工作和文化的整套流程，像是新人訓練、導師制度、文件說明等都算。你可以想成是一段從「剛進門」到「融入團隊」的旅程。例如："Our HR team has a detailed onboarding program to help new employees settle in quickly." 或 "Good onboarding helps reduce employee turnover." 這兩句都展示了它的常見用法。記得，onboarding 不只是第一天的歡迎，而是整個適應期，通常持續數週甚至數月。
