investing の語源・成り立ち Etymology
ラテン語 investire（衣服を着せる）が語源で、in-（中に）+ vestire（着せる）から成る。権限や地位を「授ける」意味を経て、資金を事業に「投じる」意味に発展した。関連語：vest（ベスト、権限を与える）、divest（剥奪する）。お金を事業に「着せる＝まとわせる」という比喩が面白い語。
Investing is formed by adding -ing to invest. Invest ultimately comes from Latin investire, “to clothe,” built from in- and vestire, “to dress.” The word developed a figurative sense of clothing someone with authority or placing them in possession of an office. From the idea of placing or committing something, it later acquired the financial meaning of putting capital into an enterprise or asset in expectation of a return.
