prolonging
延長する
解説 Definition
prolonging は prolong(延長する、長引かせる)の現在分詞・動名詞です。期間や状態を予定より長く続けることを表し、会議・治療・問題などについて使われます。
The present participle or gerund of prolong, meaning causing an activity, condition, or process to continue for more time than it otherwise would, often beyond a desired or expected point.
覚え方のコツ Memory Tip
原形 prolong に -ing をそのまま付けた形で、g は重ねず prolonging と書きます。pro-「前へ」+ long「長い」の構造から、会議・治療・問題などを時間的に先まで引き延ばす動作を想像しましょう。prolonging the meeting や avoid prolonging the discussion が典型で、単に予定を後へ移す postponing とは異なります。
Prolonging is formed by adding -ing directly to prolong; the final g is not doubled. The structure links pro-, suggesting forward extension, with long, so picture pushing the end of a meeting, treatment, or problem farther into the future. Common patterns include prolonging the meeting, avoid prolonging the discussion, and prolonging treatment without evidence. The word concerns increasing duration. This distinguishes it from postponing, which moves an event to a later starting time, and from extending, which is broader and may refer to time, space, size, or range.

prolonging の語源・成り立ち Etymology
ラテン語の接頭辞pro-(前へ)と形容詞longus(長い)を組み合わせたprōlongāreに由来します。「対象を前に長く引き伸ばす」イメージから、時間を長引かせる意味になりました。同じ語根を持つ関連語にはlong(長い)やlongevity(長寿)があります。
Prolonging is the -ing form of prolong. The verb came from Latin prolongare, formed from pro-, conveying forward extension, and longus, meaning “long.” It therefore developed the sense of making something last longer or extending it in time. English adds -ing directly to prolong without doubling the final g. The form functions as a present participle in continuing verb phrases or as a gerund naming the act of lengthening a duration.
