覚え方のコツ Memory Tip
原形 replace の語末 e を落として -ing を付けた現在分詞・動名詞で、replace → replacing。発音の中心は replace と同じで、語尾 -ing は /ɪŋ/。re-「元の位置へ」＋ place「置く」から、「古い物を外し、別の物をその場所へ置く」と場面で覚える。be replacing なら進行中の交換を表す。
Start with the base verb replace. Because it ends in silent e, drop that e before adding -ing: replace becomes replacing, pronounced with the final -ing sound /ɪŋ/. The structure re- plus place suggests putting something into the position occupied by another thing. Picture taking out an old battery and putting a new battery in the same place. In “She is replacing the battery,” the form is a present participle in a progressive verb phrase; in “Replacing batteries takes time,” it functions as a gerund.
例文
She is replacing the old battery.
彼女は古い電池を交換しています。
We are replacing the broken chairs today.
私たちは今日、壊れた椅子を交換しています。
The worker is replacing the light in the hall.
作業員が廊下の照明を交換しています。

replacing の語源・成り立ち Etymology
`replacing` は `replace` に進行・動名詞語尾 `-ing` が付いた形です。`replace` は `re-`「元へ・再び」＋ `place`「場所に置く」で、古フランス語 `place`、さらにラテン語系にさかのぼります。`place` や `replacement` と同根で、「別のものをその場所に置く」から交換する意です。
Replacing is formed from replace by dropping the final silent e and adding -ing. Replace entered English from French remplacer and can also be understood through re-, conveying return or renewed action, and place, meaning “put in a position.” Place ultimately comes through French from Latin platea. The verb developed the sense of putting one person or thing in the position formerly occupied by another.
