覚え方のコツ Memory Tip
pumping は pump に -ing を付けた形で、末尾の子音を重ねずそのまま加え、発音は /ˈpʌmpɪŋ/ です。ここでは名詞的に「ポンプで汲み上げること」を表し、pumping water、the pumping of oil が典型です。装置そのものは pump、汲み上げる工程・反復動作は pumping と区別しましょう。
Pumping is formed by adding -ing directly to pump; the final consonant is not doubled. It is pronounced /ˈpʌmpɪŋ/. In this entry, the form functions as a noun naming the action or process of using a pump to move a liquid. Picture pumping water from a well or the pumping of oil from the ground. Keep the roles separate: a pump is the machine, to pump is the action, and pumping is the ongoing activity or operation. The phrase pumping machine can describe equipment used for that process, but pumping itself refers primarily to the repeated movement or transfer.
例文

石油の汲み上げは夜に止まりました。

pumping の語源・成り立ち Etymology
中世低地ドイツ語またはオランダ語の pumpe に由来し、水を汲み上げる装置の擬音語が起源とされる。英語に入ったのは15世紀頃で、液体を押し出す反復動作を表す。関連語: pump（ポンプ）、plump（ドボンと落ちる、同系の擬音語）。
Pumping is the -ing form of pump. The noun pump entered English in the late Middle Ages from a Low German or Dutch source, compare Middle Low German pumpe and Dutch pomp, referring to a device for raising water. Its deeper origin is uncertain and has sometimes been described as imitative of the sound or repeated action of the mechanism. English subsequently used pump as a verb, and pumping developed regularly to name the act or continuous process of forcing fluid through such a device.
