解説 Definition

覚え方のコツ Memory Tip
retains は retain に -s を付けた三人称単数現在形で、語末 /n/ が有声音なので -s は /z/ と発音し、/rɪˈteɪnz/ です。retain heat、retain a name、retain a memory のように、「本来失われ得る物・状態・権利・記憶を手放さず保つ」という共通像で用例をまとめて覚えましょう。
Start with retain, meaning “keep rather than lose or release,” and add -s for a third-person singular subject. Because the base ends in the voiced sound /n/, the ending is pronounced /z/: /rɪˈteɪnz/. Use one mental image—a firm hold that prevents loss—across common combinations. A bottle retains heat, a company retains its old name or its employees, and a person retains a clear memory. Unlike briefly holding something, retaining usually suggests continuing possession or preservation over time.
例文
This bottle retains heat well.
このボトルは熱をよく保ちます。
The company retains its old name.
その会社は古い社名を保持しています。
She retains a clear memory of that day.
彼女はその日のことをはっきり覚えています。

retains の語源・成り立ち Etymology
ラテン語 retinēre（保ち続ける）から。re-（しっかりと）+ tenēre（持つ）の構成。同根語に contain（含む）、maintain（維持する）がある。「手放さずに持ち続ける」が原義で、記憶の保持や雇用の継続にも使われる。
Retains is the third-person singular present form of retain. Retain came through French from Latin retinere, “to hold back” or “keep,” formed from re- and tenere, “to hold.” This construction gives the word its persistent sense of holding something so that it is not lost or released. The Latin root tenere also appears in words such as contain and maintain.
