覚え方のコツ Memory Tip
black「黒い・黒くする」に -ing を付け、黒くする作用や黒くなった状態を名詞化した語です。the blacking of the metal surface のように of と組み合わせ、加熱・煙などで表面が黒化する場面を思い描きます。blackening より古風・専門的で、文脈によっては靴墨など黒い磨き剤も指します。
Link blacking to black plus -ing: the color word becomes a noun for the act, process, or result of turning black. Picture a metal sample darkening after heat or smoke, and attach the pattern the blacking of the surface. In older contexts, also picture a black preparation applied to shoes or another material. For the process sense, modern English often prefers blackening, so blacking may sound technical, historical, or specialized. Keep it separate from blackout, which refers to darkness, loss of consciousness, or an information restriction rather than surface coloration.

blacking の語源・成り立ち Etymology
古英語 blæc(黒い)に動名詞接尾辞 -ing が付いた語。靴墨や黒色塗料を指し、黒くする行為・材料の意。blæc はゲルマン祖語で「焼けた・暗い」が原義。関連語:blacken(黒くする)、blacksmith(鍛冶屋=黒い金属を扱う職人)。
Blacking is formed from black and the noun-forming suffix -ing. Black comes from Old English blæc and belongs to a Germanic group of words associated with dark or burned coloration. The derived noun has long referred both to the action of making something black and to black substances used for coating or polishing, especially shoe polish. The process meaning follows directly from this native English formation.
