覚え方のコツ Memory Tip
over-「過度に」＋ charged「充電された」と分け、充電しすぎた電池を思い浮かべましょう。charge の語末 /dʒ/ は有声音なので、-ed は /d/ と発音します。
Break the word into over- (“too much”) and charged (“supplied with electrical energy”). Picture a battery that has received too much charge. Since charge ends in the voiced sound /dʒ/, the -ed ending is pronounced /d/.

overcharged の語源・成り立ち Etymology
overcharged は over-「過度に」＋ charge「満たす・荷を積む」＋ -ed から成る語です。charge は古フランス語 chargier、さらに後期ラテン語 carricare「荷車に積む」に遡り、もとは「積みすぎた」が電気では「入れすぎて過充電」の感覚になります。関連語は recharge、surcharge。
Overcharged is formed from overcharge plus the past-tense and participial suffix -ed. Overcharge combines over-, meaning “excessively,” with charge. Charge entered English through Old French chargier and ultimately derives from Late Latin carricare, “to load a cart,” based on carrus, “cart.” The older idea of placing a load onto something later extended to supplying electrical energy, making overcharged literally suggest that more electrical charge has been supplied than is appropriate.
