覚え方のコツ Memory Tip
purify（浄化する）に -ing を付けた現在分詞・動名詞で、語末の y はそのまま残します。pure「純粋な」＋ -ify「～にする」と捉えると、「不純物を除いて純粋にする」という動作が見えます。purifying water、purifying the air のように、対象を直後に置く形で覚えましょう。
Purifying is the -ing form of purify, and the final y stays before -ing. Connect the word with pure and the verb-forming ending -ify, meaning “make or cause to become”: purify therefore means “make pure.” Picture a filter removing dirt and harmful substances while it is purifying water or purifying the air. These common object combinations make the meaning concrete. The form may occur in a progressive verb, as in The machine is purifying the air, or as a gerund naming an activity, as in Purifying water is essential after a flood.

purifying の語源・成り立ち Etymology
purifying は purify の現在分詞で、古フランス語 purifier、さらにラテン語 purificare にさかのぼります。purus「清い」+ facere「作る」から成り、「清い状態にする」と考えると浄化する意味が腑に落ちます。関連語は pure, purification。
Purifying is the present-participle form of purify. Purify entered English through Old French purifier from Latin purificare, formed from purus, “clean or pure,” and facere, “to make or do.” Its structure therefore expresses the idea of making something pure. The English ending -ify continues this verb-forming pattern and also appears in words describing a change of state. Pure and purification belong to the same word family.
