覚え方のコツ Memory Tip
discredited は discredit「信用を失わせる」に -ed を付けた過去形・過去分詞で、末尾は /ɪd/ と発音します。dis-＋credit「信用」で「信用が取り去られた」と捉えましょう。a discredited theory/report のように、反証や不祥事によって信頼できないと見なされたものに使い、単に unknown なものとは区別します。
Connect discredited with credit in the sense of trust or good reputation. The prefix dis- reverses or removes that credit, and -ed marks the resulting state: a discredited report has lost acceptance because serious faults were revealed. Since discredit ends in /t/, the -ed ending is pronounced /ɪd/. Common partners include discredited theory, discredited evidence, and discredited politician. The word is stronger than unknown or doubtful: it normally suggests that there is a reason the person or idea has already lost credibility.

discredited の語源・成り立ち Etymology
discredited は dis-「反対に」+ credit「信用」+ -ed で、「信用を外された」が語の形です。credit はラテン語 credere「信じる」に由来し、credible や creed も同じ「信じる」の根から来ています。
Discredited is formed from discredit and the suffix -ed. Discredit combines dis-, indicating removal or reversal, with credit, “trust, belief, or reputation.” Credit ultimately derives from Latin credere, “to believe or entrust,” through Latin creditum and French. Words such as credible and creed share the same broader root. Thus, something discredited has had the belief or trust formerly attached to it taken away.
