泡立つ
解説 Definition
foaming は foam（泡立つ、泡を出す）の現在分詞・動名詞です。液体が泡を立てている状態や、石けんなどが泡になっている様子を表します。
Foaming means producing, forming, or becoming covered with a mass of small bubbles. It is the present participle or gerund form of foam and commonly describes liquids such as soapy water, heated milk, or breaking waves.
覚え方のコツ Memory Tip
foaming は foam に -ing をそのまま付けた現在分詞・動名詞で、発音も foam の /m/ から -ing へ続きます。石けん・牛乳・波などが細かな泡を作る場面を思い浮かべ、be foaming「泡立っている」、start foaming「泡立ち始める」で覚えます。frothing は軽く細かな泡を特に連想させます。
Foaming is made by adding -ing directly to foam; no letter is dropped or doubled. Keep the visual image of many small bubbles appearing on a liquid. Soap can be foaming in water, milk can start foaming when heated, and waves can be seen foaming around rocks. Useful patterns include be foaming, start foaming, and foaming water. Frothing is close in meaning but often suggests a light mass of small bubbles produced by beating, agitation, or heating, while foaming is the broader word for producing foam.

foaming の語源・成り立ち Etymology
foamingは古英語famian「泡立つ」に由来するfoamに、進行・名詞化の-ingが付いた形です。液体の表面に細かな泡がわき立つ様子が語の核で、foamやfoamyにも同じ見た目のイメージがそのまま残っています。
Foaming is the -ing form of foam. The verb foam is related to Old English fām, the noun for foam, and fāmian, “to foam,” with cognates in other Germanic languages. The word has long referred to masses of bubbles formed on liquids. Adding -ing marks an ongoing action or turns the action into a gerund. Foamy, an adjective meaning covered with or resembling foam, belongs to the same family.
