覚え方のコツ Memory Tip
原形 dissipate「散って消える」に三人称単数現在の -s が付いた形で、主語が fog、heat、nervousness など単数のときに使う。語尾は /s/ ではなく /s/ と発音し、dissipates as ...「…するにつれて消える」、heat dissipates「熱が放散する」をまとまりで覚える。
Start with dissipate, which pictures something being scattered until it is no longer concentrated or noticeable. Dissipates is the third-person singular present form, used with one subject: the fog dissipates, the heat dissipates, or her nervousness dissipates. The ending is pronounced /s/ because the base ends in the voiceless sound /t/. Link the word with gradual change rather than an abrupt stop: sunlight disperses fog, cooling machinery releases heat, and growing confidence reduces nervousness. The phrase dissipates as is especially useful for describing one condition fading while another event develops.

dissipates の語源・成り立ち Etymology
dissipates は dissipate の三単現で、ラテン語 dissipare「四方にまき散らす」に由来します。dis-「離れて」+ supare「投げ散らす」と見ると、「散って消える」という今の意味がそのまま見えてきます。関連語は dissipate、dissipation。
Dissipates is formed from dissipate plus the third-person singular ending -s. Dissipate comes from Latin dissipare, meaning “to scatter” or “disperse,” traditionally analyzed with dis-, “apart,” and an element conveying throwing or scattering. The physical idea of particles spreading apart produced modern uses for fog, smoke, heat, and energy, and then figurative uses for fear, tension, doubt, and other feelings that fade away.
