混同しやすい語

degression

EN: 'Degression' refers to a decrease in a tax rate or a digression in speech; 'degradation' refers to the process of deteriorating or being broken down.

ja: 'Degression'は税率の低下や発言での逸脱を指し、'degradation'は劣化または分解される過程を指します。

degradation

EN: Not to be confused with 'degradation' (lowering in rank/dignity) vs. 'degradation' (physical/chemical breakdown) — same spelling but distinct senses.

ja: 'degradation'（階級/尊厳の低下）と' degradation'（物理的/化学的分解）を混同しないでください—綴りは同じですが意味が異なります。

綴りのヒント

EN: Remember it is formed from 'degrade' + '-ation', so the 'e' is dropped: 'degradation', not 'degradeation' or 'degradition'.

ja: 'degrade' + '-ation'から形成されるため、'e'は省略されます：'degradation'であり、'degradeation'や'degradition'ではありません。
