覚え方のコツ Memory Tip
原形 amplify に -ing を付けた現在分詞・動名詞です。語末の y はそのまま残して amplifying とし、発音は「アンプリファイイング」に近く、二つの i が別の音節にまたがります。amplify a signal、amplify an effect のように、音・信号だけでなく影響を強める場面も結び付けて覚えます。
Start with the base verb amplify, “to make stronger or greater,” and add -ing without changing the final y: amplify becomes amplifying. The two adjacent i letters come from different parts of the word, the final i of amplify and the i of -ing. Connect the form with practical combinations such as “amplifying her voice,” “amplifying a weak signal,” and “amplifying an effect.” This shows that the action may increase physical volume or signal strength, but it can also intensify an influence, consequence, or message.

amplifying の語源・成り立ち Etymology
amplifying は amplify の -ing 形で、古フランス語 amplifier を経てラテン語 amplificare「大きくする」に由来します。ampli- は amplus「広い」、-fy は facere「作る」につながり、「大きく作る」から「増幅する」になりました。関連語は ample, amplification。
Amplifying is the -ing form of amplify. Amplify came through Old French amplifier from Latin amplificare, meaning “to enlarge” or “to increase.” That Latin verb combines amplus, “large, spacious, or ample,” with facere, “to make or do.” The spelling of the base ends in -fy, but its present participle is regularly formed as amplifying, with the y retained before -ing.
