覚え方のコツ Memory Tip
dissipated は dissipate「熱・煙・感情などを散らして弱める」に -ed が付いた過去分詞形。原形が /t/ で終わるため -ed は /ɪd/ と発音する。heat dissipated into the air や fog had dissipated のように、一か所にあったものが広がり、濃度や力を失う場面で覚える。
Take the verb dissipate, meaning to scatter or spread until something loses strength, and add -ed for the past participle or adjective. Because dissipate ends in /t/, the ending is pronounced /ɪd/: dissipated. Imagine engine heat spreading into the surrounding air, morning fog thinning until it vanishes, or anger fading after a calm conversation. In each case, something once concentrated becomes dispersed and weaker. Useful patterns include heat was dissipated, dissipated energy, and the fog had dissipated. This shared image of spreading outward connects the physical uses involving energy or smoke with the figurative use involving emotion or tension.

dissipated の語源・成り立ち Etymology
dissipatedはラテン語dissipare「四方に散らす」に由来し、dis-「離れて」+ supare「投げ散らす」と分析されます。原義は「散って失われた」で、そこから金や精力を散らしてしまうイメージが生まれ、「散逸した」「放蕩な」へ広がりました。関連語はdissipate, dissipation。
Dissipated is the past participle of dissipate, from Latin dissipare, “to scatter” or “disperse.” The Latin formation contains dis-, expressing separation or movement apart, and an element associated with throwing or scattering. Its central image is therefore something spread in different directions until its concentration or force is lost. English later also applied the word to wasted money or energy and, in another adjective sense, to an indulgent lifestyle.
