覚え方のコツ Memory Tip
couple「二つを結び付ける」に過去分詞の -d を付けた形で、「結び付けられた状態」と覚えます。原形が e で終わるため -ed ではなく d だけを加え、発音は couple /ˈkʌpəl/ に /d/ が付く /ˈkʌpəld/ です。coupled with・coupled by a cable が典型表現です。
Start with couple as a verb meaning “to join two things.” Because couple already ends in silent e, only d is added to form coupled. The adjective therefore describes parts that have been joined and now work, move, or exist together. Picture two railway cars linked by a coupling or two machines connected by a cable. Coupled with is also common when one condition accompanies another. In pronunciation, couple /ˈkʌpəl/ simply gains the final /d/ sound, becoming /ˈkʌpəld/.

coupled の語源・成り立ち Etymology
coupled は couple の過去分詞形。古フランス語 cople を経て、ラテン語 copula「つなぎ・結合」に由来し、co-「共に」+ apere「留める」が核です。つまり「一緒に留めて結ぶ」感覚から「結合された」になりました。関連語は copula, copulate。
Coupled is the past-participle form of couple, made by adding d to a verb already ending in e. Couple entered English through Old French cople and is related to Latin copula, “a bond, tie, or connection.” Copula is traditionally associated with elements meaning “together” and “fasten.” The central image is therefore that of two things tied or joined together, which directly supports the adjective’s modern meaning.
