覚え方のコツ Memory Tip
back「背中」から「背後で支える」という動詞の意味が生まれ、規則的に -ed を付けた過去分詞が backed。語末は無声音 /k/ の後なので -ed は /t/ と発音する。be backed by facts・data・research の形で、「事実などを後ろ盾として裏付けられた」と場面ごと覚えよう。
Start with the verb back, which can mean to stand behind and support something. Add the regular past-participle ending -ed to form backed; because back ends in the voiceless sound /k/, the ending is pronounced /t/, not /d/. Picture evidence standing behind a claim and holding it up. Learn the frequent pattern be backed by facts, data, or research. This separates the relevant sense from physical meanings such as a chair backed against a wall and keeps the focus on reliable support or justification.
