覚え方のコツ Memory Tip
quarters は quarter「4分の1・四半期」の規則的な複数形で、語末に -s を付け、ここでは /z/ と発音します。1年を4分割した区間を複数扱う場面を思い浮かべ、the last three quarters「直近3四半期」のように数や複数表現と結び付けて覚えましょう。
Start with quarter, meaning one of four equal parts. In business, one year is divided into four three-month quarters, so quarters refers to more than one of those periods. It is a regular plural: add -s to quarter, pronounced /z/ after the final voiced sound. Picture four labeled sections of a business year and connect the word with patterns such as two quarters, the last three quarters, and the next four quarters. This image keeps the financial-period meaning separate from other senses of quarter, such as one fourth or a district.

その報告書は直近3四半期を比較しています。

quarters の語源・成り立ち Etymology
quarters は quarter の複数形で、古フランス語 quartier を経て、ラテン語 quartus「4番目の」にさかのぼります。語根 quart- が示す通り、原義は「全体を4つに分けた1つ」なので、四半期という意味も自然につながります。関連語は quart, quartet。
Quarters is the regular plural of quarter. Quarter entered English through Old French quartier and ultimately derives from Latin quartus, meaning “fourth.” Its central idea is one part produced by dividing a whole into four. The business sense developed naturally because a year can be divided into four three-month periods. The plural ending -s indicates that several of these periods are being discussed and is pronounced /z/ in this word.
